2X4 to 4X4 Conversion
I've been collecting parts to build a 60-63 dually for months now.
Originally I was going to just shorten the frame and keep it stock-ish height. Next game plan was to drop it and streach a cab 30 inches... Then I saw a crew cab 4X4 online... probably one of the cleanest trucks I've seen. so here are the questions that I have for the group. I'm using a 67-72 C35 2X4 frame. I started looking for a front diff for the dual offset wheels. And front hardware to hang it... haven't found 1 C30/35 4X4 in any wrecking yard, flakeslist. .. anywhere.. Was a dually 4X4 made 63-87? Will the front "hangers", cross members and etc... from a 73-87 fit my frame if I find them? Am I wasting time?

Re: 2X4 to 4X4 Conversion
You just need the wheel spacers for the conversion. If is a Dana 60 or 70, 80, you just find those. Frame spacing will determine spring mounts. Don't forget the big 3 all used Dana axles Ford drops opposite of Chevy so keep in mind transfer case input.

Re: 2X4 to 4X4 Conversion
My 2005 Ram has a 70 and have seen a dually conversion for it. Coils vs springs. Lots of newer Trucks have them.

Re: 2X4 to 4X4 Conversion
1 ton 4X4's are a little more common around here in the snow belt...
I remember seeing 73-87 1 ton dually 4X4's quite often when they were on the road... not so much any more. the suspension switch should be pretty straight forward when you find one, I assume drilling and removing all the 1 ton stuff, and just bolting it on your frame. similar with what I did on my suburban build. here are a couple in mt http://greatfalls.craigslist.org/pts/5038543279.html http://kalispell.craigslist.org/cto/5114597677.html 2 in your area, but expensive: http://phoenix.craigslist.org/evl/cto/5100014315.html http://phoenix.craigslist.org/nph/pts/5111947586.html

Re: 2X4 to 4X4 Conversion
Around here a single wheel Dana 60 front differential is going for $1000-1200. The dually front diffs are less desirable and consequently a little less $$. If you want to stay with a passenger drop transfer case, you will want a GM or Dodge front diff.
Yes GM did make a K30/3500. I've seen lots of them around here. There's still a few around. In fact my EX used to have a '80 GMC K3500 crew cab dually.

Re: 2X4 to 4X4 Conversion
I have everything from a k5.. trans/transfer case combo.
It will need to be a GM setup to keep things simple. I'm not paying a grand or anywhere close to that for a used differential. . I need a 4.11 gear set. . But I can swap gears in the rear diff easy enough. The question is how do I hang the diff.? Will I need to find a 67-72 donor? Will a 73-87 donor chassis have hangers that will work? I understand that there will be some fab work. No worries there..

Re: 2X4 to 4X4 Conversion
The springs and hangers from a '73-'86 K30 or a '87-'91 V3500 can be used.
