OK so I have what I thought was the original trans to my 72 formula the guy that built my tranny says it was made in 72 as the first numbers are 72 followed by BC which I believe makes it a buick trans? Here is my problem. It has a 9 1/4 inch tail. Everything I read on google says the ones that came with a 9 inch tail were used in the bigger cars and were actually th375s and had a 27 spline count but mine does not say th375 on the bottom of tail and it also has a 32 spline shaft. I searched google for hours and cannot find another trans with 9 inch tail with 32 spline count???? I am just trying to figure out exactly what trans it is and make sure it will work ok with my setup. I don't understand why this is so hard to figure out. I asked everywhere and nobody can give me a good answer though two people I talked to claimed they each had one in their garage. DID THEY EVER MAKE A TH400 WITH A LONG TAIL AND 32 SPLINE COUNT AND IF THEY DID WHAT CARS WERE THEY PUT IN? Two drive shafts also came with the car I measured them from the center of the holes one measured 48 and the other 52. Do either of these sound like the correct length? Thanks in advance! I am at the point in my build where I want to buy a torque converter and driveshaft and would like these questions answered first.
