Can anyone tell me how I might tell if the front spring eye bushing inside diameter on my leaf spring is 11mm or 13mm? Now before someone replies and says to "measure it" let say that I've done that and it looks to be 11mm. My problem is that I can't find that bushing size in the states. I've had two different responses from Tein/Super Pro and one said it would be 6 weeks and one said 2 to 3 months. I've also had a good response from Mad Dat and they have the bushing but just don't know if thiers is the 11mm ID or the 13mm ID. They didn't say. I just want to make sure of what I have first before I order anything from clear "down under." Is there a hard and fast rule for telling the size of the bushing that comes on such and such model of 1200? Any and all help appreciated.
