how much approx. do you think

alright dude, sounds like you got the same problem i had, pull your cage and spacer out, put the spacer over the reed cage like it is installed, and push on the bottom where it v's and see if the middle pops out, if it does lose the cage, i busted a brand new set of reeds because of my spacer, let me know
and i can explain it further if you want.
