Which trucks had trailing arms?

[chevy72blu]

Hey folks,

I have been putting this off for years, but now than I plan on an LS1 and making my 72' a DD again, I want to tackle it.

My truck is a C20 LWB camper special 3/4 ton that was originally fitted with leaf springs. I converted it to half ton/5 lug with front disks and rear drums when I cut the frame and put a shortbed on it. I removed the overload springs to lower it a bit, but it still rides like a tank in the rear.

I cant see much of a patten on which trucks had the trailing arms/rear leafs. I've seen 3/4 tons and 1/2 tons with each. Mine is a Chevy if that makes a difference.

Would it be feasible to simply buy all of the factory stuff off a parts vehicle and install it? Are there any differences I should know about?

I know I need the axle perches, springs, and arms. Do I also need a panhard bar? I assume my stock cross member will work, but the PO cut it below the driveshaft opening for some reason... Never could figure that one out.

I know CPP makes a complete kit but it sure is spendy.

Thank you!
