Cliff's notes:
So basically if you want a convertor that might be bad OOTB, no part to swap right back in while down to remove their junk, and no return shipping for their junk part, Hughes Performance in AZ can hook you up with all that.
I did not have good luck with them either.
Ordered a lockup converter for my 44RH, gave them all the detailed specs of the engine, trans, cam, usage, etc.
Converter one came in: No ring gear on the converter.
Converter two came in: Stock stall.
Called and complained and was told "oh just pull it out and ship back, you need "max stall" option" due to cam.
WTH? You had all this info up front and sound like you pulled a random converter off the shelf. Sad as I have had good luck with them before.
