Cool! Have fun with the swap. Ironically, I'm in the Louisville area this week. I was here to inspect some buses at Ft. Knox. Small world

Larry,

If back at Fort Knox again and have some extra time, let me know, if you want to meet. I live just a little south in Elizabethtown. I think I got about seven CUCV blazers from Fort Knox over the years, for a while I had a blazer farm with them for parts.

Any suggestion on what is good to use as the four bolt shifter, stock, any particular years, specific model of truck, aftermarket? Will go back and review this whole thread again too.

Also looked at " Second Generation NV4500 Shift Cover....."

Will post some more pictures.

Will do. I flew out of Louisville midday yesterday. I’ll probably have to go back in a few months to follow up on these buses anyway. Maybe we can connect then. I was actually staying in Hillview at the Holiday Inn near CC Powersports and the Tumbleweed restaurant. Most likely where I will be next time as well.

Regarding the shift tower, I believe there are only 3 GM versions to choose from. First, being the 1994 to 2001 C/K tower, which is the most common. Then there is the P-Chassis tower with is similar but built backwards as the transmission is behind the seat. Lastly, there is the 2001-2006 GM HD truck which is a tad taller due to the 2” body raise on the HD trucks (the trans cover is a tad taller as well). You don’t want to use one of those as that combination places the shifter way too high plus I swear they don’t shift as well.

The tower on the left is what you’re going to want. The tower on the right is the GMT880 HD truck tower (basically 2001-2006 2500HD 6.0L/NV4500). My recommendation would be to find a 1994 and later low rise shift tower (non-GMT880) shift lever, and upper and lower shift boots. From experience, don’t bother with the Advance Adapters NV4500 shifter assembly. Pretty much junk. There are a few towers on Ebay right now along with shifter sticks ($89 is a good price for a complete shift tower, bolts and spacer/seal). The towers are probably aftermarket but better than nothing if you can’t find a good used one.

The GM part number for this shift knob is 15982540. Being this was a P-Chassis specific knob, it is only available through Workhorse dealers

There are more NV4500 pictures in my Polar Bear Suburban thread as well.

Have fun with the swap!

Sounds good about hooking up next time. Where you stayed is interesting as it is very close, maybe 1/2 mile from where I purchased the NV4500. It is a company that has been in the power train business for quite a while. If you want to see their operation, can likely set you up with a person to give you a tour of their facility. They pretty much use Rockwell US made parts for rebuilding the NV4500s.

Thanks for recommendations on shift tower and shift lever. Did go to Ebay and found, I think an NV/GM NOS shift tower you recommended, will see when it arrives. Like the stainless steel shift lever too and got it. Still working on the other recommendations.

Thanks,
Les
