Thanks for inputs above. I got it figured out already. Here are a few pics. Yes, without a little courage, critical analysis, some input from other Supra owners ... and a little luck ... this at first seems an impossible task left up to the experts for the big bucks. But, when I'm not skiing I like to have all this extra fun. I guess that's why they call it pleasure craft marine. I work on my 4Runners too.
The pictures tell the story. I'll check with SKIDIM to see if they have a recommendation for a replacement bracket, but I may just get mine repaired by a welder. Thanks again.
