I have been looking for a decently priced NV4500 for my 1957 LCF to put in with a throttle bodied 350. I have yet to find one with a brake but that would be near perfect. It seems to be easiest to swap in a dodge gas nv4500 since they have mechanical speedometer. To me this is the way to go using an advance adapters plate and keeping the existing clutch setup.

Earlier today I happened into a 1998 Diesel NV4500 off craigslist at a steal of a deal that is now my trading material.
