Inliners International Forums General Discussion Engines GM SI alt bracket for 235

The 57's gennie generator went south, so I'm replacing it with the modern GM SI alternator.

Does anyone know of a ready-made bracket designed for the 235? I can always cut-n-weld to modify the old generator bracket, but for the sake of time, I'd just as soon buy one. Everything I've seen on the web, though, as been for small block applications.
