I plan on using a 6 speed crossmember and TH400 454 ss truck mount for my turbo car. Can't find the PN for the mount and I don't trust my dealer to look it up. It's impossible to find it in the catalog on GMpartdirect.com.

 

454 SS truck mount? you just use a standard auto trans mount. you just need an energy suspension one that has 2 exta threaded holes for the bolts to go into instead of one hole in the center, remember to get the spacer block to lift the trans up 2 inches if your using a M6 crossmember.
