Making a G20 a 4x4???
As the title says fellas, I want to make my 1991 GMC G20 conversion van into a factory looking 4x4. I have a near mint drivetrain to put in it and I was just wondering if any of you pros have done this before??
I want to make a good Bug Out Vehicle(BOV).  The chassis I have is a SM465/205 with a Dana 44 front and 12 Bolt POSI rear. I do have a 3/4 Ton and 1 Ton drivetrain I can use(Dana 60 front, Corp 14 bolt rear and Dana 60 rear posi) Thanks fellas for your input. Patriot

Re: Making a G20 a 4x4???
wont the shifter on that 3 speed be 2-3 feet to far back......
i'd find a divorced np205 to go behind the transmission in there now.. fab up a crossmember (current thread in the 4x4 section) and get yours drive lines made.... just swap the rear axle with possibly some custom lift springs and then do something like a b52 kit on the front....

You would need to find and adapt a hydraulic clutch setup for sure though.

Re: Making a G20 a 4x4???
not to be a buzzkill, but aren't 4x4 vans notorious for bent frames?

 they are basically unibody.I have seen this done before, but it required massive modification to the front of the van structure as the engine cross-member and 2wd suspension mounting points are all in the way of a solid axle. Years ago a company called Pathfinder made a kit to "bolt-in" and add either a leaf sprung or coil-over solid axle. Leafs are very hard to do unless you want to have your mounts sticking well out in front of the van. Coils are a bit easier, but still require massive amounts of fabrication. Also you have to consider the differences in steering between a van and a solid axle truck. Not to try and steer you away from this, heck I have a 94 G20 sitting in my garage that I want to do the same thing to, and I have a full 1/2t driveline sitting around to swap into it as well. Check out Pathfinder Vans

Re: Making a G20 a 4x4???
I have a HP60 that came out of a Pathfinder van, was built in 85 or 86.
After reading some of the stuff in that site, I don't know if I'd want to buy anything that have... *Small block engines and big block engines have different bell housing patterns. *4-speed trannys can be installed if you use the rare 465 tranny top that has the shifter mounted to the rear of the shifter top. Used in the mid 80’s in 1 ton GM trucks

Re: Making a G20 a 4x4???
Looks like you've had several months to ponder this. Are you talking about bolting your van body to a 4wd 73-87 pick-up frame? Obviously some modding would be needed in certain areas but it sounds like the result would be worth it.

Re: Making a G20 a 4x4???
I would do it if we still had are 76 Chevy g10 with a built sb350, th400 15"x10" tires in back 15"x8" in front thing had more power than my blazer sb400, th350 fun burn out machine for a thirteen year old kid but neighbors landlord hired a tow company to take some cars off his property and they took it off of are property with the cars they were there for and it was never seen again.
 imagine this with slot mags and lowered it would be the exact van

You could always fab-up a Ford style radius arm from suspension.

There is one for sale on CL in my area, been for sale for a while. I think it`d be a cool idea, weekend camper, beach cruiser.

Re: Making a G20 a 4x4???
I just spotted this while looking for parts on craigslist. If you're interested in making the drive down I can go check it out and take pics. looks like it would save you alot of fab work and give you a rust free body.
