Howdy, I have a set of 6112s on the front with 5160s on the rear. The set has 28k miles and the driver's side front has started leaking. I'm a little surprised as I bought Bilsteins thinking they wouldn't need to be rebuilt as often as Kings or Fox. I would say 98% of my driving is on the street.

I'd like to be penny-wise and pound-foolish and replace just the one leaking shock, but the few places I've called and a Google search didn't turn up any part #s other than just a new set of 6112s. Do any of you happen to have the part number of the shock they use in the 6112 strut assembly? Or would you suggest I just replace both front shocks with a new set of 6112s or something comparable that would pair well with my 5160s?

Thanks in advance.
