5 speed swap, Anything else while I'm there?

Got my TKX and new pedal box from Hawk's. Also got a so-so clutch that will work fine for the TBI 305. I'll change it for the big bad motor at a future date. What about a brake booster upgrade, I'd do a hydroboost but I've gone all new so far and the only new source I know of has a 9 month lead time and I'm doing this in about two weeks. Won't get one from the junkyard. Any improvements over stock booster on the vacuum front? No long lead times.
I've read Quick's Torque arm write up but it's soft on actual recommendations so I haven't got one or even made up my mind on that yet. I don't have a shift lever yet and the one I'm thinking of might not work and would **** off everyone on the planet but me. Original Cuda pistol grip. Will upset the mopar guys at it rips off them, same for chevy guys for the opposite reason but, Damn! they feel good and look cool at least to me. Already got some poly trans mounts to go in. So, what am I missing?

Seriously considering TKX swap myself. Did you get the entire swap kit from Hawks? Kinda spendy, but seems to include everything short of fluid and DD box for VSS conversion.

If the swap if from automatic to manual don't forget the pilot bushing in the rear of the crankshaft. Always like those original pistol grip shift handle myself.

Nope, I got a 20% off coupon from summit racing I won during the hot rod power tour in june that made the trans kit much cheaper but they didn't have the pedal box that I got from Hawks. Without the discount, Hawks would have been the cheaper alternative though.

A TKX will handle some pretty serious Hp and torque I'm thinking. And sure make for a fun driving machine.
