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!
