LIL help??

It should bolt right up to the big block bellhousing. You might get lucky. The E Body transmission might have two shifter mounting points on the tailshaft housing. The front mounting point is the one where the Fury shifter should mount. The 65 trans probably has a ball & trunion U joint so you'll have to deal with that. Might be able to get a driveshaft from a 66 or later car that's the correct length, or you can have one made.
