Converter question

OK, so now I am really confused. What you are saying makes a lot of sense to me and is what I generally though it would be but I just rec'ed a winger of a question from a parts company.

I though it would be nice to use new nuts in the torque converter. So this company has two types. Mopar and non mopar. So I scooted where I am keeping my stash of parts..well away from my wife's normal walking patterns ..and I find it is MOPAR unit...so I sent that info back to the company that it is a chrysler unit.

I get this back in return mail.. Is it a factory/stock torque converter or is it a stall converter?

Am I missing something. This guy has helpend me to find a part so I want to buy other stuff as a thank-you.

thanks
ian.
