Mopar 9 1/4" rearend
I have the tsm rear disk on my Cuda (8 3/4) and love it. I have heard problems with the calipers with ebrake provisions sticking, I got the non e-brake kind with ss lines and have had no problems so far, they've been on the vert two years now. I'll never do drums again if I can help it.
