toploaders are nice but i rather have something with a overdrive i love my mustang i drive it daily gotta be fun to drive on the highway too.

 

The TKO isn't going into my 66. Too big and too heavy. They are more difficult to shift than a T5. My 66 currently has a T10 and I would stay with a 4 speed it's just the brake booster clearance problem as stated before. That will make me have to use a hydraulic or cable clutch. This isn't my daily driver it's just a toy so OD isn't mandatory. Nothing wrong with 4.11 and 1.1 4th
