Converting an automatic 74 Swinger to a 4 speed

It's possible but it isn't cheap, most annoying part is installing the pedals. I wanna say it was around $2500 to swap my '74 but I used mostly new parts clutch and shifter linkage wise. I was on the fence for about 5 years on doing it, I collected parts on and off 2 other times before I bit the bullet. I honestly have no regrets with going to a 4-speed in the car, it'll be better with a gear in the car.
