Please tell me that gasket doesnt cost $99...!
Mopar prior to 78 used the Chevy bolt pattern, but chevy had the stat recess in the intake, not in the stat housing like Mopar. But they have some cool O-ring housings. Check oout cool-view, Im sure you can adapt that to a Mopar...Just use Dex-cool to keep your engine block Hemi-Orange!
