I have a 33 gtr which has a twin os push type with the converter. I have purchased a nismo twin coppermix which is pull type like it had in the first place and i planned on just taking the converter out assuming that was all i needed to do. Somehow the slave cylinder is on the original pull side with the two spots to drill into untouched . Dont quite understand how it all works but does anyone know if i need extra parts when i take the converter out. The car is up on hoist with the mechanic stuck on it. Any input from someone who has come accross this would be much appreciated!!!
