axle interchange? chevy
I've been searching the web but haven't been able to find out any info. Does anyone know which axles I could swap under a 1995 chevy C-20 van? The current conventional doesn't do well in the weather so I'd like to find a posi unit either from another van or pickup.
Gear ratio doesn't really matter, just as long as it's posi, I just don't want to do alot of refabing (moving spring plates etc)
Thanks!

I'd be asking the junk yards, they have a comptuer program that tells them what is the same and what isn't. I'm not sure if posi was an option in their vans in those years. A cheaper solution would be better tires. Try an A/T LT rated tire. When I did this on my '92 E150 I gained A LOT of snow traction.

hehehe I've tried all sorts of tires on the van, doesn't seem to make much of a difference. Only way I've been able to go well in the snow is to put chains on it.
Weight shouldn't be too much of a factor either, I use it for service at my HVAC company. Actually it's probably coming close to being over loaded.
I've thought about calling the wrecking yard but some of them around here get a little snotty if you arn't buying anything from them. Even if their is a posibility of buying but you don't come right out and say your getting it from them they really cry about looking it up

As for asking the 'recycling yards' - if they don't want to give you any information, take your business elsewhere. This, I have NO problem doing.
(Rule #1 - If YOU don't take care of your customers. . . . someone ELSE will.)
For the C-20, instead of a posi unit, try the 'locker' that came in the 10 bolt rearends.
If memory serves me, a 10 bolt is a 10 bolt (except for the 'new style' that GM put into cars in the 70's) and 12 bolt rearends are 12 bolt.
Same / Same, so to speak.
Now, drum to drum. . . . I dunno.
Let us know how it goes.

Your van probably has a 12bolt in it. If you can find a same-year Z71 4x4 in the junkyard, they have a 12bolt limited slip in them. You should be able to swap carriers, keep your gear ratio, and have a bit better traction.

C20 thats a 3/4 ton isnt it?Is it 6 or 8 lug?
GM used semi floating 14 bolts in alot of there trucks(the six lug 3/4 tons)and full floating 14s in most of the heavyer rigs
I cant see there being a 12 bolt,streanghth issues.A 12 bolts ring gear is smaller then a 9inch.

From what we were told when we bought the van it's supose to be a "heavy half". The rims are only 5 bolt, I don't remeber what the axle cover has for bolts, going to have to go recount. 5 leafs in the back and coils in the front

It probably has an 8.875 ring gear semi-floating GM axle if it has five bolt rims. Ratios of 3.08, 3.42 and 3.73 were the most common.
The funny thing about vans is that the "3/4 ton" models are equivalent to "1/2 ton" pickups in GVW, axles, brakes, etc. My 1974 E-100 had 14 inch rims!
