A833 to 727 Swap - Parts List?

Call me crazy, but I am strongly considering swapping my ‘68 dart’s 833 to a 727. It has a 340 (416 stroker), about 515 HP. Los Angeles traffic, plus my wife not being as confident driving the 4 speed, and I want her to be more comfortable driving it.

I’m trying to come up with a parts list, I have searched around and found some info, but most everyone is doing the opposite swap. This is why I have so far:

727 trans/converter/cooler, looking at a kit such as 111138P1 from Summit or JEGS but I am also considering buying these parts separately. TCI Auto 111138P1 TCI Street Rodder Transmission Packages | Summit Racing
Neutral safety switch
Floor shifter
Kickdown linkage (Lokar probably)
Driveshaft - 833 is shorter so I’ll need to modify or get a new driveshaft, right?

What am I missing?

Thank you in advance!
Whatever you do please don't put your money in TCI! Use Cope transmission or other reputable mopar trans companies. Others will chime in and tell you the same.
