I put a T5 in my Nova a few years ago and I used a Turbo 400 mount. I cut off the pad and welded it back on at the same angle as the pad on the trans. I had tried the wedge shape piece but I just couldn't get it to work quite right.
I would suggest that you do the same, weld the mount on the cross member to match the trans pad. My T5 came out of a 92 v8 Camaro. FYI I was able to use a rubber mount from a TH350 on mine, it bolted right on.
