1 ton running gear on a 70? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

shelby987 · 12-02-2005, 09:32 AM

I have come across a 1980 4x4 van with 1ton running gear for a decent price, and I wanted to find out if the axles will swap into a 1970 k20 without any mods, or what specific fabrication would be needed to make them fit.

Also, does anyone know, will the rear be a dana 60 or 14bolt in 1980?

The rear should be a 14-bolt.Who did the conversion?Was it Quincy or a TerraVan?You`ll need to I.D. the parts like the front axle and t-case.Is it a right-hand differential up front?Are you sure it`s a Dana60 in the front?Most conversions did use the heavier components/But,as vans go,they`re called 3/4tons(20 series) with 5-lug wheels and 12-bolt rears.So,a 1t van could just have the same stuff that would be under a 3/4t pickup.
If it`s a Dana60 r/h,it will pretty much bolt right on to your springs.There may be some work to get d-shafts and steering together,depending on what all you have.Nothing difficult,though.The rear will have staggered shock mounts and you can either change them to match your`70 location or change your`70 to staggered.That will require another cross-bar for the rearward shock.As long as it`s a GM-friendly drivetrain,it won`t be a big job.

honestly, I know nothing about the van, came across the ad, and its near my family on the east coast where I will be for the holidays, so I figured maybe I could take my truck, and a trailer with me on my way home, just wanted to see if it was a possibility first. I will try to find out more specifics, the ad reads that its original from the factory 1 ton 4x4 van....were these not optioned?

I ran onto one a while back for a reasonable price so I called about it.It had a Furd D44 in the front {Drivers side drop} and a 14bolt in the rear.I have been told some had D70's in the front,but I think those were Quigleys.

shelby987 · 12-02-2005, 11:12 AM

there is a d70 front axle? never knew that.
Currently this van is about 600 miles away, so what questions do I need to ask, and what pictures do I need taken to be able to get the best and brightest minds on this board to be able to answer what running gear is in it?

Yeah there are D70 fronts.They came in some 70's and 80's Dodge 1tons,some Dodge W400's and in some of these 4x4 conversion vans.They also are in the 04'+ Chevy and GMC 4500 and 5500 4x4's. There is other vehicles that they came in.The early Dodge ones were closed knuckle.It should have d44/d60/or d70 cast into the housing on the pumpkin.
