GMC rear end ID

So I recently acquired a basket case 1975 GMC Sierra 10 8' Stepside that originally had a 250/auto (long gone, along with the SPID tag). Tried to research what rear end it came with but not much luck so far. The Chevy counterpart shows 3.73 std and a 4.11 optional. It'll be a while before I can get to where its stored for a visual, but am trying to plan what all to do with it... i.e. keep it, part it.... whatever. Already know the bed parts are going to be sold.
Any help??????

Re: GMC rear end ID

If you have the Chevy data then GMC would be the same (rear axle ratios were not released differently Chevy vs GMC).

Re: GMC rear end ID

Thanks Keith, suppose there is any $ diff depending on the ratio?

Re: GMC rear end ID

Price all depends on the buyer. Eitherway you'll have a hard time selling a 10 bolt for more than $100 using craigslist...
