Just a few pictures of the last few weeks of me going through the 1994 NV3500 I bought for $100 to replace the original one in my 1990 C1500 with 220K miles on it. Each image has a little write up that includes information that I couldn't find online or in factory manuals. Also, I'd suggest buying parts from Cobra Transmission. They are very reasonable and they do a good job.
If you are going to attempt to do this, get the Kentmore pallet and a factory GM manual. Bought my manual from a local GM garage for fairly cheap because they had a spare. You will need a shop press and a bearing splitter to remove synchro hubs. My 20 ton press worked just fine.
Also, to install the speedometer ring on the back of the main shaft, coat the main shaft with oil. Then hang on to the ring with pair of pliers and heat it up for a minute or so evenly with a propane torch. Set the ring on the shaft square and it will fall right on.
