I have a pair of front mavins that measure 13" eye to eye unadjusted. I bought these, mounted them, they were too long, and then took them right back off. I did borrow a heim from one of them and put it into one of the shocks I was trying to replace......so you will have to by a heim from marvin. He charges like 8 dollars for one. 260 plus shipping.
