1987 3/4 ton 4x4
Hey,new to this area.Was on 60-66 forum ,I sold my 1964 stepside and got a 87 full size.Anyway,it's been a while since I had one of these,so my questions are...I know I have a np208 in it,can I put a 205 or 203 transfer case in it? It has a 700r4 or will I need adapters? Second is the bed is shot and I have an 89 bed,can I put this on without too much fab work and how bad will it look.Also have a .030 350 to drop in it.As for lift,I don't want to go 4'' anything around 2-3'' would be fine,any suggestion? Thanks G-REX

Re: 1987 3/4 ton 4x4
I have a 1987 4x4 3/4 ton as well. I have had it for at least 8 years and it has been a good truck. I just removed the entire front end for a complete rebuild of everything. All the parts are now painted and ready to go back in but now I am painting the frame so I am not sure where I will stop. My truck has a dump bed lift on it which is great around my farm. My 350 is fuel injected and was a new GM crate engine when I bought the truck and the turbo 350 was also rebuilt so it has about 60K miles on the drive train. You can go with a 2" lift but in my case I installed Rancho helper springs in the front which were a pain to install. I am not sure how much it will lift the front but I just wanted to lift it about an inch as the rear is high enough. I have had over 75 bales of hay (3500 lbs) in this truck and still did not have an issue with it.

You can put a 205 on a 700 if you have a 205 that was originally off a Turbo 350, will need the sleave and adapter, also a 2" spacer that goes between the tranny and adapter.

Re: 1987 3/4 ton 4x4
In order to swap in the 203 you will still need a 2 inch spacer and both driveshafts will need the length changed.

Re: 1987 3/4 ton 4x4
The 350 turbo is already bolted up to 203,came out of a wrecker.I'll need driveshafts and possibly moving cross member.I im going to put in the 350th/203 in place of 700r4 and 208.But was messing with truck and trans and 208 are working fine.Shifter linkage was off,adjusted and seems to work ok. Thanks for reply

Re: 1987 3/4 ton 4x4
I'm going to put the 350 th/203 in ,and take the 700r4/208 out. The 203 has the part time conversion.The front driveshaft seems like it will work.(bolt up on transfer case).The rear is a fixed yoke on 203 ,and a slide yoke on 208. I'll need a telescopic driveshaft to bolt to the fixed yoke on the 203.So if I can find one out of a 1973-1979 3/4 ton ,it should bolt up to rear. Sound right? Thanks
