My 55 has a 4 link. So does my 32.
IMO- takes alot of work, time & money to get one dialed in right- especially a home built one.
What motor? How much power? I see you want to drag race it.

IMO- your best & cheapest option is reverse eye de-arched leafs. That will get you plenty low. I'm speaking from nearly 50 years of hot rod experience.

If a 4 link is burned into your mind & there's no convincing you otherwise- Then do your homework. Mine is all pro built because w/ slicks & 700 hp- I tore the 1st one right out of the car. I have fully adjustable parallel 4 link w/ a diagonal link to keep it centered. Because the car is low (coilovers all the way around- no bags)- the driveshaft tunnel was pie cut & raised at rear & pockets had to be built for the top 2 bars because at ride height- they were above the floor under the rear seat. On the 32- only one end is adjustable & I use a Panhard bar for centering & a roll bar to keep the wheels on the road.
My 4 link in the 55 was built by Williams Classic Chassis Works (all out drag race 4 link w/ many gussets & braces) & the 32 is TCI.


Here's a few "kits" for trucks to look over.
