Stock replacement umbrrllas or have they been cut for modern style? If origonal, it really doesnt matter imo. I would bet that the guides are pretty well worn too. Best to check them.

Those or similar.. the full one goes on intake and the umbrella on exhaust. Thanks I believe to Joe for helping me with that last year as the old OEM style where all 16 are the same are no longer available.

BTW.. 3/8" valve stems the part number for seals is P4120492, found my bill for them while looking for where I got my torsion bar seals from.

I got my seal kit on ebay for 10 bucks + postage. Right place, right time, Mopar factory kit.
