so the spring centering pin holes on my jeep perches, D30 and 8.8 appear to be smaller diameter than the ford perches. IF i am right.........will this be of any concern when i install the 44 and 60. so the springs will just be a little sloppy but not when i crank down on the u-bolts right?

dumb question? i don't know :)

don't know what kind of jeep you have but a lot of them have 5/16 centerbolt vs the ford which all have 7/16....if it is 5/16 i would have the holes punched to a bigger diameter but if it's a 3/8 then i'd leave it alone....the ubolts will keep them in place (go with bigger just cause it's stronger and ford centerbolts hardly ever break vs a chevy or especially jeep in which it's pretty common)....at least it will be simple to center though
