Help: Any other blocks use MP R3 4 bolt main kit P5249669 ??

[autoxcuda]

Mopar Perf R3 4 bolt main cap package P5249669

Do these fit?:

-X-block

-340 "resto" block

-any other block

Trying to get info on this for buyer before I take it to swap meet. It might really help a guy with an old X block kicking around that lost it's caps over the years.

They should fit any of the aftermarket blocks that are machined with the 2 bolt caps. Should also work on a TA block. Not sure about aftermarket blocks already machined for 4 bolt main.
