Which flex plate for MP 175k converter?

Thanks 70aarcuda, you saved me the aggravation of buying the wrong parts.

Sorry 66dartman, the price is right but the application isn't.

Looks like Mopar Performance does not have a SFI rated flex plate for the 'econo' converters using 5/16" bolts. They list a non-SFI flex plate with part number P4876821 that sounds like it should work. The corresponding bolt kit for this is P4876820. And wouldn't you know it, the non SFI rated plate and 5/16" bolt kit is more expensive than the SFI rated plate and 7/16" bolts. :roll:

The B&M flex plates are $75, but I don't see one for internal balanced 6-bolt crank and a 904 transmission. Are there any other neutral balance flex plates with 6 crank bolts and 5/16" TC bolt holes available?
