Nv4500 to np208 shifting linkage
« on: August 28, 2015, 12:43:53 PM »
so the I'm finally underway with my nv4500 swap in my 81 k20 ( actually the only thing 81 about it at this point is the cab and the title hahaha) anyway so I got a killer deal on a 92 tranny so I had to get it. Yea id rather have the closer ratio nv but I paid $180 for my tranny,bell housing, and slave cylinder and it's in great shape so I'm not complaining. Any way I'm going to be using an np208 out of an 86. I've found the answer to every little detail except one and that is the transfer linkage being in the way of the nv4500 shifter/boot. I know it will "work" with some minor adjustment,but this is a restoration project that I've gone all out on and I really don't want it looking like crap. There's gotta be a way to move the linkage somehow to be out of the way and still look semi stock. Can someone help me out with this? Maybe some suggestions on ways to rebuild linkage? Any suggestions are welcome.

Hmmmm we may need some Picts to help you. To make sure I understand the question, are you saying the shifting boot from the trans is interfering with the range of motion of the 4wd shifter. Sorry just Looking for some clarity.

I'm sorry. That wasn't very clear. I'm saying that without modification the trans and transfer boot will be touching each other if the shifting linkage for the np208 is left at stock adjustment. I don't have any pictures of it on my truck because I have the cab off the frame right now.

Ok you may need to find away to offset the tranny shifter moving it towards the steering wheel. This may involve some cutting ,welding, fabricating etc
