Bellhousing to center of stick mount measurement

I accidentally posted this over on the automatic forum this morning. I'll ask an admin to delete that one.

Does anyone have a measurement of the distance from the face of the bellhousing (engine block side) to the center of the stick mount for an A-body 833? Say from a 130 tooth flywheel bellhousing to a Hurst shifter mechanism with the trans in neutral.

I've found all other dimensions out there, except this. We're looking to put an 833 in a little hot rod thing a buddy is assembling. Trying to figure out where the shifter will wind up before plunking down the money on the transmission.
