XC Falcon Coupe diff change, lowering block install, fuel sender retainer install

[@shaunallan9141]

Love the coupe, just interested in the rpm range after the diff ratio upgraded? Whats your open road rpm like in top gear is yours 4 speed still? I have a XB coupe with the 4 speed and factory borg warner diff and was looking at fitting a Ef/ El ute/wagon rear end with the disc brakes. Many Thanks

Nice coupe man! I still have the m75 bw diff. I wouldn't mind upgrading like you have. Did you have to cut the diff down? I thought most newer car had wider track diffs.

No, only 3m wider from memory. Would love a 9 inch but can’t justify the money yet. I’m surprised how well this combo works, bolted straight in.

XC 1547mm compared to EA,EB,ED 1557mm and EF,EL 1559mm. So

Thats great news! I wouldn't mind finding a diff assembly with lsd and disc brakes but thats probably going to be difficult. I used the 75 series bw in my escort, but has moser billet axels with ebay copy truetrac lsd. It hooks up very no dramas. My current m75 in my xb looks very sad.

Xw 1502 around a inch shorter either side 👍 .. xr shorter still
