14-bolt questions

[poncho-mike]

I've been looking around for a 14-bolt FF with 3.42 or 3.21 gears for a few months now. In my search, I've turned up a few rear end. Not being a 14-bolt expert,I've got a few questions about a couple of rears.

First, I found a 14-bolt FF with 4.10 gears and limited slip differential (according to the option list on the glove box). It's out of a 85 GMC 3/4 ton truck. The guy's wanting $350. That seems a little high to me, but I don't know what the factory limited slip adds to the value. What do you guys think?

Secondly, I found a junk yard with a number of 3/4 ton Chevy vans. There are two vans with 14-bolt FF rears. According to the label on the hood, one of them is a 4.10.

I'm more into stock 4x4s. What is the deal with the van 14-bolts? Are they a different width? What are the spacings on the spring perches, and are these the same as 3/4 ton or 1-ton trucks? The price on the 14-bolt van rears is more reasonable, $200 each.

I also found a 14-bolt rear out of an 89 Suburban at the same junk yard, but I don't know what ratio it is. The glove box emblem was gone. It was a big block 2WD according to the VIN. Does anyone have a book that would tell me what the standard axle ratio is for that setup.

Thanks for any help you can offer.

Van WMS is 70" compared to 67.5" for SRW trucks. The local yard my buddy and I usually hit wants $200 for 14 bolts.

the limited slip adds value only if you want one. the carrier is different than the open one, and you cant get a locker for it, but ive heard rumors you can still weld them with acceptable results.

there are 2 widths, 67" and 63"

you should probably just go on pirate and read the 14 bolt bible
