Quick question on mounts.
Otherwise you should be fine with the factory ones, just clean them up and give them a good coat of synthetic water proof grease in the upper mount, and on the upper isolator .
And also put a light coat of the same grease on the upper shock shaft the goes through the upper mount, just some good P.M. !
FYI, you should be able to get factory upper mounts for a lot less than $280!
Here's a handy tip. Use a stainless steel nut to attach the shock to the upper mount so that when it comes time to disassemble the nut won't be all corroded. I got mine at Ace hardware.
