hello folks anyone ver had an extension housing leak no gasket was used according to ford dealership. i have tried super blue rtv and formagasket #1
to no avail thinking about making my own gasket anyone tried this yet?

 

First off Welcome Aboard. I would Check with a mazda dealer or a transmission shop to be safe because I don't Believe (not 100%) Ford made the mazda B-Series During 86-93 Generation. Ford Took over building the B series in 1994. Some Transmissions do have Liquid Gaskets mostly manual Transmissions which i'm asuming you have Since most of those trucks were manuals. While I was At Louisiana Technical Colleage we tore down a Toyota 5 speed Transmission with Transfer Case. A lot of work but we goter' done.
