I guess a 7A is similar- if you're talking about the windshield fiberglass around it-- which I just finished...
I bought the West system with the extra pumps and I have a 1/2 of the big can of the 105 resin sitting here and the hardener in the small 7 oz. can is just about empty.
HTH.
edit-- hardly used any of of the milled glass fibers just a bunch of 2 inch strips around the top.
