metrics usually require offset arms check in speedway catalog and you can set up front end with your arms with the camber you like to run and measure from the cross shaft to center of ball joint and order or look for offset arms with the measurement you get say like 10" for r.f. and for l.f. say 9 1/2. hopr this helps

as was said look in a catalogue, talk to the manufacturer. they will be closer to 8" right and 9" left though. i think the stock arms are 8.5

The UB machine ones are good, put them on a metric last spring. Price is right too.
