Best Performance Mod for a 1965-1966 Mustang (DIY)

[@jesimss]

Great video. Best I’ve seen for torque box install in an early Mustang.

[@wolfthornhawkridge5705]

Awesome video, explained a lot. I always thought the 68 Mustang handled better than the earlier years. Also, I appreciate that you didn’t take the entire front end of the car off to install the torque boxes.

[@danielbargas3377]

I’m restoring a 64 1/2 d code and have replaced the entire floor pan from firewall to trunk plug welded every inch apart. On the jack alone you can already see the difference in deflection is amazing. Will be adding front torque boxes now

[@petersessler7124]

Great video. This is exactly what I needed. I'm building a 69' from scratch and there aren't any other videos that explain the process as well as yours. Thank you

[@klupeeteable]

go and see Jo daddy garage ,,, he does whole mustangs..good luck

[@67ST4NGSTER]

Nice Vid. Keep em coming. Waaaaaay back in the day, I started rebuilding my 67. It was pretty rusty too. At the time I thought the right hand torque box was rusted completely out. Nothing left at all, so I replaced both, not realizing it only came with the one side........LOL. Turns out some mistakes aren't really mistakes after all :)

[@goldysgarage189]

great vid - so glad it was posted in January - a winter project - not a summer one.

[@deanhenthorn8674]

Great vid. Never heard of a torque box before or you guys...so two birds with one stone. Wish we were closer to MO. s

[@morganleblanc730]

Very good video. Very clear install.

[@gregbowen9209]

Any concerns about moisture and dirt getting trapped inside the torque boxes and becoming rust traps?

[@GatewayMustang]

Nope! We spray weld-through primer on the inside of the torque box before we install it, and at the rear there ends up being a small passage that any water and debris can escape through.

[@Charlie_Prinz]

Great information and presentation, thank you. 👍👍👌👌

[@cardo1111]

Excellent vid appreciate the comprehensive explanation 👍🏽

[@ripburroughs]

You stated those are Dynacorn Torque Boxes, are you using the 3654 & 3655 WT for 67-68 for Coupe’s & Fastbacks and modified slightly for the 65-66’s ? Great video for fitment, thanks

[@paul87buick]

Very good video well done

[@danemoll4065]

Nice work. Great mod.

[@suttonfarms2343]

Great video. We're restoring our '67 fastback right now. How do you prevent rust behind these panels (i'm paranoid about rust....not sure if it's justified...), but wondered what could be done to ensure long life for metal.

[@brettkelly2297]

Hi mate , I know this is a few years ago , but was hoping to install mine without removing the front fenders like you did ? Any issues with doing this ? Access ? Etc

[@red2003xlt]

I inherited my mother's 66 mustang coupe. If I install L & R torque boxes do I still need subframe connectors? I plan on-street driving and maybe going to a 4 bbl holley

[@bransonfleischman2233]

On a street car, you could get away without subframe connectors and just go with the torque boxes. But they work even better in conjunction.

[@limey2899]

hello great video, where do you get your torque boxes from.....do you have part numbers? Thanks

[@JB-qu5vk]

Thanks for the video - Is that a 67-68 torque box Dynacorn Coupe/Fastback part or a 65-66-67-68 convertible torque box Dynacorn part?

[@davevan8864]

Good info!! I have owned my 66 2+2 since 1975. Ballpark how much would one pay to have these installed. My car is kinda mild but sure these would be good to add. thx

[@waybachwin1747]

Thank you buddy. Very helpful

[@willybones3890]

Awesome! Thankyou SO MUCH for this vid!!😀

[@mikehouser8308]

Hope to see you all in Sturgis in 2022

[@the-driver-66]

Very informative video and a must when we start on my ‘66. My only question is regarding the last triangulated piece you fitted. Is it a mud and moisture trap? If so I would make a decent sized drain hole.

[@GatewayMustang]

The torque box gussets actually leave a small opening between the torque box and frame to prevent water/debris build-up.

[@the-driver-66]

@@GatewayMustang 😎, thank you for your reply.

[@TheSmellofGas]

Great video! I need to consider adding this mod to our current GT350 Tribute...👍

[@jimmydang9808]

great info. Thanks!

[@dennisparass5531]

My 65 mustang has aHotchkiss suspension with sub frame connectors. Would torque boxes be duplicating the rigidity that I presently or do the add anything?

[@Fritter70]

Great video thank you

[@seanweiss4647]

Thanks for this info. When you cut the bitch for the back piece to the firewall how do you seal all the bare metal so it doesn't rust

[@FINfinFINfinFINfin]

Weld through primer.

[@cryptosully2357]

how do you keep it from rusting out behind the boxes you left it bear metal ???????????

[@MCFABRICATION]

@gatewaymustang What brake setup is that?? Part number of kit number please!

[@dannyv3243]

How much would an upgrade like this run me?

[@anomamos9095]

It's a little concerning that a prop wasn't placed under the cross member to take some of the weight of the engine off the frame rails before the torque boxes were welded in. I have seen some of those vehicles sag over an inch on the lift.

[@tezdesignful]

What company makes those particular torque boxes

[@GatewayMustang]

The torque boxes used in this video came from Dynacorn

[@kevincady5613]

Great video! Where are you located? I have a 65 fastback that would do quite well with this addition.

[@GatewayMustang]

Thank you we are at 10461 North Service Road Bourbon MO

[@Glens1965]

Nice Job!!

[@paulnoone8103]

Hi, nice vid. Any info on what brand of torque box? as the link below dont seem yo work for me. Thanks

[@GatewayMustang]

We use Dynacorn for all of our sheet metal.

[@paulnoone8103]

@@GatewayMustang Thanks for that, i did look for them at cj's and could only see dynacorn 1 piece units. Do you separate them or buy them that way, and where from. Thanks again.

[@GatewayMustang]

The torque boxes come as a left and a right side with two panels per box, and the torque box gussets are a separate part.

[@michaelannen4168]

I was so confused owning a 67 coupe. I thought someone removed the passenger side

[@klupeeteable]

Why didnt you do anything on rust prevention inside ? The steel torkboxes are not very good prevent against rust. Spray weldtrue on them or undercouting These things rust out easy.. !

[@FINfinFINfinFINfin]

He did spray weld through.

[@wholeshot1556]

[@joe-hp4nk]

The mustang front suspension was crap to begin with. You're just adding a band-aid to a bad design.

[@GatewayMustang]

Joe, this has relatively nothing to do with suspension but rather an integral chassis brace that not only makes the car safer, but improves overall handling performance by making the unibody stiffer.

[@Galactusz007]

@@GatewayMustang Don’t mind Joe, as he’s obviously clueless of this concept.

[@Galactusz007]

Joe, you are un gran pendejo, lol.

[@russellweber4334]

Usually when a comment like this is made, it is a troll who I doubt has ever even changed the oil on a Mustang.

[@joe-hp4nk]

@@GatewayMustang True, the unibody needs stiffing. I owned a 66 mustang GT 289HIPO back in the early 70s. It was a lot of fun, but it seamed ford went out of their way to do things the hard way.
