Hey Greg,
So just to clarify your explanation,you dont use a crush sleeve or solid spacer at all? Where do you make the reference mark at?
I am getting ready to set up my 9" soon and I have been doing alot of reading on the subject.
I would like to try your method,sounds like a better way.
I will also be going up to Carlisle this year.I hope to get to meet you and the Battlestar !
BOB
