2 tips for this... #1- speed makes a "universal lower leaf spring perch" that works great for this application- and they are CHEAP! part numbers 917-20249-lh (and the same number ending in rh) they are 19.95 each. these allow the use of a more modern shock in the rear. for the axle itself, we used the speedway weld on spring pads-p.n. 545-85090. 12.95 a pair. the pin on the leaf is gonna be a different size than the hole in the middle of the pads- but fear not! you can get thesoe at Autozone, Napa, whereever...and a grade 8 allen head bolt (5/16-whatever thread/41/2 inches long) works peachy. once you have that tackled, and the rear end is located (are you using the stock rear, or the one from the camaro? they both fit nice, and the 10 bolt camaro rear may be a bit fresher...mabey) you can then relocate the shocks to the outside of the frame using the original shock upper mounts. (they are a bitch to remove without an air hammer of substantial strength) and do your c-notch. ( I used 3.5 inch tubing for this. 1/4 wall. ) and boxed it from crossmember to crossmember with 3/16th plate. (no need for overkill there, unless you're running a gooseneck trailer-which I kinda doubt.) crap. I just realized I forgot to show how to mount the bumper up front. More Monday!
