I used the bell housing from my SM465 and put it on my NV4500. I drilled and tapped the old mounting pattern on the NV4500 transmission. one hole is halfway into the original mounting hole for the NV4500, so I tapped it and threaded in a large bolt, then cut it off flush with the NV4500 case, then drilled and tapped my SM465 holes into it. The down side of doing it this way is that the bell housing now bolts to the transmission from the front inside the bell, so you can't remove the transmission from the bell while it's in the truck. I don't mind this, so that's how I did it. I then used a clutch release arm and slave cylinder from Novak to use a hydraulic clutch. I've been driving my truck for a couple years now with no issues.
