Re: 62' GMC 3/4 ton project
CFab is right. The easiest way is to mimic as closely as possible the factory configuration. Finding a factory style NV4500 bellhousing shouldn't be too difficult or expensive.
I too wanted to use a later cast iron bellhousing with driver side clutch fork because they are cheap and plentiful. But when I set the engine into the truck I saw that there was no room for the clutch fork. The cab floor/firewall drops right down almost on top of the driver side of the bellhousing. So I went and found a 60-62 V8 bellhousing and all is well. This also allowed for a no hassle installation of the slave cylinder and push rod. I'm done with this part of my build, so if you'd like to see this type of set up feel free to come by and check it out. I'm pretty close to Santa Cruz, at Summit Rd and Hwy 17. Shoot me a PM if you're up for it. I'm home all weekend.
l'd also say that the factory bellhousing crossmember is probably going to need to be removed. You'll need a crossmember for the rear of the NV4500 anyhow and the factory one will probably be in the way.
