65 Dart 727 trans mount?

What rubber snub? I had a 65 dart that I put a 340 with a 727 in nd had no problems.

There is a chunk of rubber bolted in the trans tunnel. Directly above crossmember mount. I'll attach a pic tomorrow. So in the previous pic with the trans and crossmember not fitting, the tail is up against the rubber snub. Need the rubber mount in the crossmember to be 1" shorter...
