As far as I know, the front A-arms are Spitfire size. Rears are similarly sleeved in steel, not sure what they're from. 1.385" O.D., 0.441" I.D. (approximate), and the outer sleeve is 1.250" L.O.A. Inner sleeve is 1.488" L.O.A.
The OEM part has: "EX31525" and an "AR" in raised lettering in the rubber.
Hope that helps, Darren. If you do source 'em, please let us know who/where?
