I finally got me an nv 4500. Can't wait to start getting it installed. Has anybody done this swap recently I know I looked at old forums a while ago just wondering if any new ones were around. And if anybody knew how much I should be expecting to have a rear drive shaft made not worried about the front one right now just the rear once I can get it driving with the new transmission

Currently the truck has a th350/205. Not exactly sure on the year, the guy said he thought it came from a 96. I read your thread on when you installed the nv 4500 into one of your trucks and I like how you used the original style bellhousing is that still holding up? I'm hoping to do the same thing I've looked over your thread a couple times.

Yep, that baby is running great with no problems. Be sure you get a bell housing with the 5 1/8" center hole. If you need any measurements from a stock SM465 trans to see if your NV4500 is the same or not as far as the front bearing retainer, shaft length, pilot length, etc. let me know.

Going from an auto to manual is a bit of work.
The shifter tower says it's an early (93-95) trans, and not a 96. 96 and later had a squareish shifter mount. I actually have a 96 GAMM trans in the garage. The trans to BH lower bolt hole centers are slightly more than 9.75" on the early transmissions.
I think I see a barcode sticker on the top. Try to get the 4-letter code off it. Advance Adapters has a NV4500 document and a general conversion guide. I have the NW4500 doc pdf but haven't found it on their site in a long time. It's called NV015
The 4x4 trans output isn't going to work with the NP205 w/o machining the (205) case for a large bearing and swapping the input. There are figure-8 adapters to bolt it to the trans though.

Quote from the doc:
"During the first two years of the NV4500, Chevy offered this 5 speed with a 6.34:1 1st gear; 2nd 3.44:1; 3rd 1.71:1; 4th 1:1 ratio, and a 27% overdrive. It was also the first year that Chevy changed the bellhousing-to-transmission bolt pattern. This transmission is ideal when converting your vehicle, providing an ultra-low 1st gear. GM, however, only produced this particular ratio during these years. The major
complaint of this 5 speed was stiff shifting and noise in 3rd gear."

Thank you for the help. I planned on using a 208 transfer case because I'm not going to use this for serious off-roading and I figured it would be a cheaper route to go and easier route.
