Datsun mini truck 521 restore part 15. Ball joint conversion, disc brake conversion.

Can you install d21 Hardbody lower and upper control arms on a the old kingpin trucks? The 320,520,521 and 620. What does it take. The camber is handled differently between balljoint and kingpin knuckles.
I decided to see what it will take to use all d21 suspension on a 521.

15:52 God i wish mine would come out that easy. Im pretty sure mine is seized completely. I've even tried an air hammer with the intent of shaving off a few bad threads.

yeah I got lucky. I just finished fixing all broke fender/headlight bucket bolts yesterday. As of today I don't have anymore broken bolts that I know of. I have had a few in bed, frame and body.

@NissanNut74 I'm constantly looking at suspension alternatives. If it all came out smoothly. I'd keep the set up longer, but things are starting to force my hand. I'm pretty sure I'm the first one in here since it was put together from factory.
