Hi Bryan, will try to make this race (been a few years)....just need to get my new TKX 5 speed installed this winter and should be ready to go!
If you need help on installation I have done 2 TKX installations on my 62 409 cars. i have some pictures.
You need a new replacement shifter ( with bolt on handle ) to match the factory 4 speed shifter location. New TKX 5 speeds do not come with the correct shifter to fit the factory 61-64 4 speed shifter location.
I used the factory 4 speed tunnel cover for the TKX ( it was moved slightly from the 4 speed location were it was screwed to the factory floor pan over the rectangular factory 4 speed hole in the tunnel.
I purchased the correct TKX shifter from Modern Driveline - they knew which shifter was needed to fit my 62.
I have a “template for the rear transmission mount” that I had made to bolt to the factory frame mounts.
The mount I had made was curved to use the factory frame mounts, since the TKX has a rear transmission mount located about 3” further back from the factory BW 4 speed or Muncie 4 speed rear transmission mount.
I had the driveshaft shortened and switched to 1350 U joints ( from stock 1310 u joints) with a billet carrier bearing and changed to a front slip joint driveshaft section required with a slip joint driveshaft. All for my 530 HP 409 stroker motor and for 9” Ford rear end installed last year.
