4L80E guys - what dust cover are you running?
 

I'm having a devil of a time trying to find one... the plastic "universal" one from Ebay just plain doesn't fit.

I know there's the cast aluminum one from GM (15765623), but damn... $120?

I also ran across this sheet metal one from GM as well (15000206), but I can't find any pictures of it. It's way cheaper, but I'm hearing it doesn't utilize all the bolt holes on the dust cover flange on the transmission.

Anyone have any input on this?
