Wayne, Sorry it's being a pain for you. I just recently mounted a 91 to a mount for a Funtana and it was a challenge too. It seems like I had to do some grinding of the mount material to get it to work but it did work out fine. But that is a Hangar 9 mount. I wouldn't remove the carb bolt. There must be some other mount that will work. One of the other guys on here must have come across that and will chime in on this. You might have to relocate a few of the T nuts on the firewall. If you have to move them it's a good idea to fill in the unused ones with a chunk of dowel rod and epoxy. Also if you do have to fill holes with dowel rod make sure it's flush on the inside of the firewall or it could interfere with the new T nut.
