I understand this was a weird model year because they used 2 different frames, outside frame spring mounts and under frame spring shackle hookups. My truck I believe was under frame, no mounts on side of frame. I am looking to install a decent rear that would work with a 5.3 LS.

Ed '37 GMC T-18 w/ DD 4-53T, RTO-610, 6231 aux., '95 GMC running gear, full disc brakes, power steering, 22.5 wheels and tires. '47 GMC 1 ton w/ 302, NP-540, 4wd, full width Blazer front axle. '54 GMC 630 w/ 503 gasser, 5 speed, ex fire truck, shortened WB 4', install 8' bed. '55 GMC 370 w/270, 420 4 speed, grain, dump bed truck from ND. Works OK.
