Van Rear?
Are 67 to 72 Chevy Van rears the same as the 67 to 72 trucks? 12 bolt?? Are parts interchangeable?

Re: Van Rear?
G-series vans are different, I believe. P-series vans are similar, chassis-wise, to the C-series trucks.

Re: Van Rear?
i believe van rears have a greater offset to them than truck rears

Re: Van Rear?
Just wondering, as there is one for sale local for $50 & he claims it's a posi. Were the vans 12 bolts?

Re: Van Rear?
Yes the g20 van rears are 12 bolt. they are a leaf spring rear and the shock mounts are opposite each other LS Rear and Right side Front . So if adding to a truck you would have to change out all the perches but otherwise it should work. As far as a posi well would rather doubt it but you never know Oh of course there is no provision for a panhard bar so it would have to be mounted to the frame and lower shock plate. I would just find another one if it was me.

Re: Van Rear?
Wasn't looking to change the whole rear end. Just the inside posi unit. Wondering if it would fit into the present 12 bolt I have.

eaton made a posi for the 12P and 12T ends. they were both used in g-vans and trucks from the early 60's up into the late 70's maybe longer. I have never switched one personally but the Eaton catalogs call for two parts Might go to a rear end rebuilding shop if you have one close. The cases housing for the posi are differant for the gear ratios. Under a 3:42 uses one part number and for a 3:73 and up uses a differant case. Last edited by mbgmike; 01-14-2009 at 08:26 PM. Reason: wrong part number |
