I have a set of used 4.30 gears. They were in an 04 Cobra for 3000 miles, I was going to put them in my Mark, but decided to keep the 3.73's that are in there for now.
$100 + shipping

430's hey man will they bolt right into the marks rear. also do you have the speedo gear that came with those gears. thanks man
i wanna put these gears in my track/street mark 8 im bringing out in the summer time.

I thought 04 Cobra had 31 spline rear end?

they do have 31 spline, but that has nothing to do with the ring and pinion gears.

i do not have the speedo gear, but they are only ~$10.. the gears will bolt into a mark's rear just fine. you will probably want a limited slip of some sort, but i would assume you have that or plan on it already.

sale pending
