That is what I put on my TA. With the T-tops they really help cut down on the squeaks

Thought so that's good. My driver side mount is a bit rusted.

Re: Sub frame contacters

If you are running a y pipe buy the UMI connectors. If you are running exhaust inside the transmission tunnel then buy the BMR connectors. If you or a friend or relative can weld then forget buying them and just make em. The outer connectors are very simple to make. The drivers side is a straight bar with two saddle joints and then another bar at 45* to the transmission tunnel. Look at the current last page of my build thread and you can see how they mount and look.
