47-54 Trailing Arm Suspension

[Sixshooter44]

I have a 55 series 1 3800 truck and would like to swap in a 12 bolt I have out of a 68. I really like the truck arm setup but I should just do a 4 link and be done with it.

IMHO, the narrow 34" frame of the 55 is not going to fit well with a trailing arm set up. Also, the 68 rear is a bit wider than the 55, I'd check to see the difference. I agree with you that a four-bar set up would fit and work better in this case.
