I tried to find the pic I saw of your stringer's/floor, I couldn't find it. You shouldn't have to cut anything, the front mount is about 1 1/4" thick, it's flat, and "sticks out" less than the pulley/altenator.
I looked at a Tahiti one time to buy and it had a Panther pump also. It's engine mounts looked homemade as well. Now I'm wondering if Panther engine mounts are supposed to look that way...
