Automatic to 4 speed Conversion in '65 Formula S

My first post here, but long time lurker, I'm also on the EVBC list. So...I have a '65 Barracuda Formula S, California car, no rust, owned it since 2003. I took it apart in 2009 and am now starting back in on the restoration. I've decided to convert the automatic to a 4 speed. I like original cars, so the conversion will embody the look of a factory F/S 4 speed car, including the R1234 shift bezel, shifter hump, and Hurst shifter. The original 273 4 bbl engine and 3.23, 7-1/4" axle will be retained. I do, however, want to use a later 833 overdrive trans. Since I have none of the conversion parts yet, I'm looking for advice on flywheel, clutch, pressure plate and bell housing. I know the OD 4 speed has a larger input bearing retainer, and the stock 4 speed bell housing hole either has to be enlarged or I need a different bell housing. I also know the stock clutch was a 9-1/2" unit. Instead of finding a stock bell housing and paying for machining, would I be better off with a different bell housing? I also know the 9-1/2" clutch parts are limited and I have not found a new stock flywheel, so going with a larger diameter setup is probably the best way to go. I also want to stay with stock pedals, and am concerned about firewall flex, so a pressure plate that requires a lot of force is not desired (although I could reinforce it). I also know I will need a new driveshaft to replace the ball and trunion. So recommendations on what bell housing, flywheel, clutch and pressure plate that will bolt in nicely behind the stock 273 and fit the 833 OD trans. is what I'm after. I'd like to stick with stock parts if possible. Going to the Cupertino CA Mopar Rally swap tomorrow. What should I look for?
Brewers has everything you need. I own a automatic car and a 66 Dart with a 4 speed. In my opinion all the work and expense for a 4 speed isn't worth it. Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists
