5 bolt leaf spring rear info - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1972chevy4x4 · 03-11-2003, 09:56 PM

Hello,
I am building a 1968 GMC short-step at this time and the truck has a six bolt leaf rear. I am converting to five bolt leaf rear and having trouble locating one. I know an original five bolt leaf is hard to come by so I was told I can convert a newer 73-87 rear to fit, but what is required? Looking to put a set of 3.73 in it. Any info will be helpful. P.S. how much wider is the newer rears than our older ones. Thanks Dan

70-72 rears are 1.5 inches wider than 67-69, thats all I know, dunno about the conversion, I have a 71 C-10 leaf truck and I got a posi rear sitting in the sher for it too

Check with board member gregsplace-in the past he has had what you are looking for and he lives about 15 minutes from Wichita.

Classic Truck Mag had a artical on this for a coil spring rearend
but they did touch on the leaf spring rearend.
Find a 12bolt with the gears you want and then have the saddle plates changed the fit the 68. Try Early Classic.com
