702 GMC V-12 powered '62 GMC 1-ton

[locomotive breath]

I've got a 9" with 3.00 gears out of an '82 Econoline sitting in the shop floor. Not wanting to sell it but it may help narrow your search. I'm not sure if the van is the same width as the pickup but it does have the 5 on 5 1/2" bolt pattern like the trucks. I'll check the overall width for you in the next day or so. I think the 1 ton springs are also wider than the 1/2 ton springs but spring perches are easy to change.
