1/4 mile times

no im not worried about all that,
I think almost all distributers do have the shaft and bushing but this set-up since its the older discontinued model i think the weights themself hitting the plastic center peice is the max... instead of an adjustable bushing.
But i called the original owner and he said he put it in brand new and thats how it came.. and he always just set it for total and ran it like that... as long as it didnt have problems starting then it was fine.?
