thanx for the reply mike, but i have 2 sets of 5.38's & a set of radials so i'll probably go that route. i have another friend working on a set of 5.57's he thinks is still available. but that might take a while, so the .38's will have to do. 5.13's would probably drag the motor down too much, even with the radials. but i appreciate the offer. thanx dave
