Slept on this last night....
so the decision is to wait till the end of the track season to replace it.
reasons:
-- Road Atlanta only track I do that needs 5th. all others are 4th. (AMP/Barber)
-- time to budget for it.
-- then after the season, no rush to get it in to be done...
-- as JARblue mention, check out Liberty Gears ,if learned never to say never
Thanks all in helping educate me, always learning and trying...
