Kmember/mtr mount Q

If you are trying to use the /6 centerlink, you'll need the thickest mount you have to gain the needed clearance- if you have the V8 centerlink, I think you'd want to use the thinnest mount you can to keep your center of gravity as low as possible (and provide max hood clearance). Keep in mind you may have to go thicker or thinner and/or use spacers to get the header fitment right; each individual car is a little different.
