GSX , I have no shop but if you removed it, I'd be glad to help you check it and reseal it. All my pals in the shops have retired or sold their shops and went into other fields.
It would be easy to look yours over and take care of things with you.

I live in KC north. I have a 66 barracuda with a 904 that has 33K miles on it, and works great, but leaks. Do you do transmission work or can refer me to someone in the area that can ?
