I have done the reverse of this swap a few times, but not recently. Have a 3.5k mile 400th sitting on floor in garage, that I decided not to use. The hole in the tunnel yes, as well as hole in the floor for stock clutch linkage set up. Mine doesn't have a bolt in tunnel with a SM465. If I do go the NV4500 route, I won't be using a stock hydraulic pedal setup, unless I stumbled upon one in a junkyard. Haven't looked yet anyway. Just as easy to mount an aftermarket racing clutch pedal/mc setup to the firewall or adapting it to the stock mount. Fabricating a bracket off the bellhousing and using either a push or pull slave, depending on fork clearances. Sure I have a spare AFCO mount sitting on a shelf. Or just using a hydraulic throwout bearing. Then running a braided line between the two. Simple, basic racing setup.

If snow isn't too deep around my truck (leg still in a brace), I'll measure both and get a few pics for you also.

The turbo 400 from bellhousing face to mount is 27 15/16. Maybe someone in a warmer climate can get the measurement for the sm465. Snow is too high around my truck.
