I am not ready to screw up my daily driver so I guess I will make my own bracket.
Update 2. I have a weird shifting issue that I thought was the engine turning on and off the AFM or DOD. Now I think it is actually something with the transmission. It works fine when driven hard but when I slow down for , say, railroad tracks and then give it light acceleration, a hard jerky condition makes me accelerate harder and the condition goes away. Trouble is that now I am speeding and in traffic it sucks. I have tried the method of keeping it in Manual #5 gear and it still happens. I have tried trailer mode too. So a big POO to that! I have looked into Trans-Go shift kits and they mention the issue. I may have to drop the pan and try that.

I hope you don't have the problem I had with my six speed.

It started shifting rough so I made an appt to have it checked out, then it started getting really bad on the 60 something miles down to the shop. By the time I got there it wouldn't shift out of 1st. They said a planetary broke and chewed up the whole transmission.
