Yes, I'm the Chevy guy here
A machinist friend and I did the swap with a nv4500 swap manual. The tranny is out of an early 90's GM 1 ton with 6:34 granny gear.We made an adapter plate from a piece of 1" plate since there are no adapter plate for the early tranny. We used a GM 4wd mainshaft and installed a GM input gear in the NP 205 so no adapters on the mainshaft. We cut the input shaft on the NP 435 and the NV4500, cut an index pin on one shaft and bored a hole in the otherand made sure the overall length was correct. We used a welding procedure where we preheated the input shaft and welded the shaft with 100,000 psi tensil strength wire. No problems with the input shaft after 5 years of use. We used the original Ford cluch plate. We used a GM tranny mount and had to do some alterations to the crossmember. We lengthened the front driveshaft and shortened the rear. We had to relocate the transfer case lever and cut a hole in the tranny cover. I didn't notice any increase in mileage but it made the truck go faster. Total cost including the tranny approximately $1300.
