Early A trans mount

My two cents: I ran the single bolt version for years in my 65 Barracuda, 340 4-speed. Never had a problem. The mount is bolted to the crossmember at the bottom, and to the trans at the top. Can't imagine why the lack of a tab would be a problem. I did get a two bolt version a while back and put it in last fall. Urethane, if I remember correctly (it's hard to keep up). If you need to be concourse correct, pay the $$$ to get the two bolt version. Otherwise, the single bolt version will work just fine.
