Installing my 360/300hp Mopar Performance crate motor is being held up because I cannot get my windage tray. Several people have told me the Mopar Performance one is the best piece to use (part #P4529790), but it is on backorder, and no hope to have it available anytime soon. Anyone know of an equally good, or better one? Tired of waiting, as is the mechanic who has my car occupying a bay.
