K30 Van 14bolt FF ratios?

[BlitzK5]

Anyone know what gear ratio's come in these things? A local junkyard just towed in a 1ton van and I was thinking about heading out there to scoop up the 14bolt.

Is the van 14bff the same width as the truck 14bff?

Mine came out of a 78 G30 van and it has 3.73's in there now..

The van version is 70" wide versus 67" for 3/4 and one ton.

Yes.....Be forewarned... The vans have ratios that you aren't used to seeing on "normal" 1-Ton axles.

The one I bought had a strange ratio (like 3.75) also, though I can't remember now what it was.

It's posted here somewhere (quick search oughta find it) along with a table of ratios that are in the van-width axles.

Other than that, the van axles are good for about 3" extra width overall and keeps you from needing wheel spacers to get the wheel track to match the D60 up front!!!

I measured my axles yesturday, the 14bolt was 67" but to my surprise the 12bolt was only something like 64"??
I have used a 1,5" spacer on the 12 bolt(1,5+1,5+64=67"), and I was expecting the 14bff to have the same width, but apparently not.
My plan was to use a 1,5" spacer on that one also (want to do the 8 to 6 lug conversion.. )
but now I guess I can't.. ?? It's going to look ridiculous..
So now my dilemma is that I can't use my 6 lug MT wheels in the rear, and when I looked at 15" with 8*6,5, I found a few thanks to you guys here, but no matching set or combination with 6*5,5 bolt pattern. The problem is that I still have my 10bolt up front and I want to have matching wheels.
Any body have any suggestions? (plz don´t tell me to find a D60 or going 8 lug up front.. it´s too much $$$ here in sweden)

Thanks // Sebastian

(edited for bolt pattern)

you need to look for 8 on 6.5 not 170.
