Hello Everybody I just joined the site a little while ago and I have my first question. I have a GM NV4500 with the higher 1st gear ratio. Since I already have the trans I want to use it behind the 6bt that is getting installed in my 67 Kaiser M715. Has anyone used a GM 4500? I know I will need to get clutch linkage worked out, but what kind of adapter will I need to use to mate the trans with the engine.

I have read of it being done by others. Some have had problems with the splines getting torn off of the smaller output shaft or in the coupler to the transfer case.

I use Gm Nv4500 96 & up in all my conversions and I just have dodge input installed when they are built.

If you have a 1st gen GM NV4500 the bellhousing bolt patteren doesn't match up to the Cummins bellhousing ,if you are going P-30 adapter than it will work .

Since you have a 6B from a Dodge? Why not keep it all Dodge, why reinvent the wheel. With it being Dodge you have proven reliability, parts availability. The hydraulic clutch set up has been addressed here, so I don't see any problems.
Yes I'm biased toward Dodge.

GM NV4500's are all the lighter duty version than the cummins/V10 transmission. The input shaft is bigger in the NV4500HD, but so is the mainshaft and 5th gear. The 92-95 GM trannies can be redrilled to bolt up to later bellhousings, but you cannot swap a dodge or any other input in.
