Stupid Valve Stem Question

I'll be ordering a set of Pro-Stars in the next few days and I love the look of an all-metal valve stem. That being said, check these out:

http://www.jegs.com/webapp/wcs/store...tegoryId=11613

I'm looking at either the top ones (306-2900-4) or the bottom ones (306-2913-4). The only differences I can tell between the two is that one is Outer Bolt Mount, the other is Flush Inner-Bolt Mount; and one is .453/.625" Diameter Valve Stem Hole , the other is .453" Diameter Valve Stem Hole.

Can someone please explain these differences to me and give a recommendation on which I need? 15" Prostars without tubes.

Thanks!

I'd probably go with the inner-nut mount. I've had good luck with them before. I wouldn't have a clue as to the actual size of the hole on the Prostars though. Maybe somebody can measure for you, or call up Jegs and see what they recommend.

I like the outer mount ones better. If the nut ever came loose (slim chance I know) with the inner mount ones the stem would just shoot out I would think. I would also check (if you care) that inner mount ones are NHRA legal like the top mounts are.

Thank you for the replies, guys.

Does anybody know the actual size of the hole on the Prostars?

Just some advice from me. I had those on my Elky, and since they are chrome and are just a little bit heavier than the sock rubber ones, any time the tires turn it puts a load on the rubber they have a tendacy to crack. I replaced them a few times before I figured it out. I would just go with stock ones, but if you want a show look get them.

If you race at the track with those wheels, you need the bolt on stems to be legal. Sorry i don't know the size. When i ordered mine, I blieve it would work on either size like the 306-2900-4 will.
