I want to convert my 84 sub from two wheel drive to four wheel drive. I have heard all the holes all already in the frame, I would just have to grind off the rivets and bolt up the leaf spring mounts. If anyone has done this I would greatly appreciate the help before I get into a project I cannot finish.
 
I'd suggest crawling under a 4x4 and taking some frame measurements, then doing the same with your 2x4. I think you'll find that they aren't the same.

Also, the transmission is different, plus you'd need to add the transfer case, the correct steering box, etc., etc. It's really much easier to just sell your 2WD and use the money towards a nice 4WD.

So get out that measuring tape and see if the parts will fit!

Go for it. The hardest part that I can see would be the front crossmember. Anything is possible with GM.

Has anyone done this? what happens to the spring pocket from the 2 wheel drive?
I'm not saying it can't be done, anything can be done if you have the tools and enough beer

The whole 2wd crossmember will unbolt taking the entire front suspension with it. Except for the idler arm wich will have to be unbolted seperately. You can even sell the front suspension settup to someone that would like disc brakes on there 2wd 63-70, there are a few looking for this settup.

The frames are completely different and will require much custom fabrication to make it work. You either need to find a 4x4 burban frame to set your body on, or you need to sell your truck and buy a 4x4. IMHO

'85 K5 : Run it til it breaks, then fix it and go again!
 
I had looked into this when I had a 2wd pickup and it looked like it would require the whole front of a 4wd frame to be grafted on. Unless you really REALLY love this truck, it's not really worth the work IMO.
On Furds it's real easy, but not on chevys

Check over on Pirate, there is a thread about the same thing ( I think its in the Chevy section).

frames are the same
crossmembers are different
get the naysayers to break out THEIR tape measures
I run a 2WDR one ton frame using all 1/2 and 3/4 ton brackets
**** all to it but to do it
 
I sure hope 77chev is right...

me and some friends have an 8 door suburban (yes, stretched like a limo) thats 2WD.. we have a K20 donor for parts, that project starts someday. maybe mid-'02.... anyhoo we were planning on at least SOME fabbing... if the frame rails are the same that will be a huge help.

My suggestion would be if you know anyone in the car biz, have them keep an eye open at auctions for a rust bucket 4x4 Sub, around the same year as yours. Or look in the papers. They should be cheap, either way. Put your body on that frame, and sell the extra parts, engine etc.
