THAT's it. Left hand thread / Right hand thread. Thanks.
OK, next question - If I switch from TR-4 to TR-4a (or TR-6) lower A
arms, does that undo the lowering effect of the later trunnions? My
car is low enough already, and messing with spring spacers doesn't
sound like any fun at all. I've got two weekends before the next
race to get this done. It sounds like the later A-arms are a direct
bolt on for the earlier car with the welded in lower frame
pivots. It may also eliminate the need for the reaming and
spacers. It would probably also eliminate the additional camber gain
- not sure that's a plus, but everything else would be a positive.
Joe, your TR-250 front end is getting more attractive as we go along... :)
