California Performance Transmissions (aka Art Carr) can provide a 141 tooth flexplate with 50 oz. balance. It is a special order and price was around $300 last I heard. You will have to call them direct at (714) 901-3777 to place an order. I also have a spare out in the garage I may be willing to let go.
Headed off tomorrow to pick up a 1990 engine from an F150. Long block that seems to be in good shape . I wanted to get an HO but this was close by and the right price .
