I was cleaning out the garage yesterday & stumbled across this trans crossmember/mount. The trans mount has a large through-style bolt rather than the small stud & nut like am used to seeing on 68-70 b-bodys. I have seen these before but its been so long ago, I can't remember what vehicles had these (darn old age !). The crossmember was very dirty so I couldnt read the part number. Any help would be appreciated.
