Its true that GM used a Ford 3 speed manual trans in some of their cars. I had a 1965 GTO that I bought right after I graduated from high school in 1980. The car had the 389 Pontiac motor and a Ford 3 speed manual in it. The car was not running when I purchased it for $1000.00 dollars. I located a 1969 Pontiac catalina wagon with a 428 and turbo 400 in it. Built that motor and trans and installed it in the GTO. I had to do some modifications to get the trans and driveline too work. That GTO had some interesting combinations as built new. The 389 with a Ford 3 speed manual, power steering, manual brakes, A/C, one speed wipers (slow), console vacuum guage, and no seat belts. Car was still wearing its faded original silver paint and the white parchment interior looked exceptionally well for its age. I also got a 1966 over the counter Pontiac three deuce manifold and carbs set up for the car included in the $1000.00 dollar purchase price. Rebuilt that also and installed on the car. Sold that car in 1984 for $4500.00 and though I made a killing. The only things I still have of that car some pictures and the original 1966 water neck for the tri-power
