What's a good sprag for TF 727

Yea that about what mine looked like but it broke up so much that the flex plate broke and cross member was all that kept it in the car. In the end i replaced the transmission, drive shaft, flex plate and the shifter after a piece of metal went up it and jammed it. Never could get the metal out even after disassembling everything i could. All told about 5500.00 plus time in 1982 dollars. Buy the best stuff you can be safe in drag racing it not what with break but when will it break. Good luck
