Default Why?

I am building a new diff with OE and aftermarket parts. In my search I found out that the vent port on a Corvette is the same as any other Getrag diff.

GM Price $30.00
Mopar Price $9.04 w/tax

Just a suggestion, you might get better responses with a more descriptive thread title.

I can't tell the difference. Neither of them have a part number stamp in them.
