what about a speedo ?

yes, I've had a nv4500 in my 80 model dually that I tow my jeep and dragcar with. We put the tranny in behind my old 350 that was in this truck and my other dually. Put the bellhousing on bolted tranny up used jacks and stands to support everything. Then put the tranny mount on bolted crossmember up and drilled two new mounting holes. Cut and balanced front half of driveline at a buddies shop. The speedo was replaced with a electric version I found at the junkyard out of a 90-91 suburban. I found a wiring book on ebay for the 90-91 model gm trucks and subs. Found wiring info for the speedo and made it up. Fixed a adjustable drac module that drives the speedo head from pulses from tranny. My biggest problem has been with the hydro clutch. The thing seems to want to eat slaves and masters. But I can say that it has helped the truck out alot. I wish I would have done the swap years ago. Maybe by now I would have the clutch issues fixed.

odee, i got the same problem with my 86 dually, with a heavy duty 4-speed. it eats slaves and masters too. replaced both atleast 4 times in the past 2 years. thinking about getting the linkage out of a 77-81 clutch truck, and installing it.

crossy, sounds like you are as fast as I am working on projects. I start them, or plan on starting them only to never finish.

Question for the guys that have done the NV3500/NV4500 switch. Does the old bellhousing, say off of the SM465 fit onto the NV4500? I thought I saw they have removable bellhousings, where the NV3500 is a full piece transmission? Is this right? The problem I am going to have is I want to run this change on a 4x4 truck. Just saying that caused me to not want to do it. Good luck to anyone getting ready to tackle this job.
