vroom vroom, now i am confused. LOL.
i am talking about bearing spacers, not wheel spacers.
are your 6 lug rotors using the factory style ball bearings ?
if so, then i guess you might not need a bearing spacer.
mine uses the newer roller type wheel bearings and you need a bearing spacer that slides onto the spindle. it wont work if you dont.
i was told by the place i got my kit, and other people, that yes, you can use an adjustable rear prop valve along with the factory style combination valeve. that is exactly what i am currently using now on my 57.
in problem #5 from my previous post, i am talking about just the bleeder. the threads that the bleers screwed into was worn, and i had to wrap it with teflon tape to get it to not leak air when i cracked it while bleeding.
hope this helps, and make certain your 6 lug rotors are capable of using your old bearings. i ahve never heard of that, but i could be wrong. that is another advantage, having newer style roller bearings. they hold up much better to the radial tires and road conditions we have today.
