Here is where is install goes south in a hurry. This is the first time I have run into this issue with SPL parts. I measured the diameter of the bushings. Both at 1.492". Then I measured the ID of the holes in the arms. 1.421" for both.
That's 0.071" differences.
Should have anywhere from 0.001" to 0,003" difference. So now I have to call SPL on Monday and tell them. So that they can ship me new bushings with the proper OD's.
