There are a couple of issues with installation of the Quaife in SOME of the MTX-75 cases. Terry can answer all of these questions. His number is (616)874-1148, email
secondline@ameritech.net. I just got my transmission back from him. He installed a Quaife and an updated shift tower and it works great! That Quaife really makes a difference in cornering. I haven't tried any hard takeoffs yet because my new clutch is still breaking in, but I'm sure it'll work as advertised! BTW the Quaife has a lifetime warranty.
