Well, it is not a direct, drop in fit. You will need to elongate a few of the holes in the firewall to get it to fit, but hundreds of guys have done it. There are some tech articles and info on the internet.

Is your car a 87-93? If it is, then since you do have the 95 proportioning valve (which is actually a combination valve, with a PV and a safety shuttle valve combo) then I would use the 95 combo valve to keep from having to get a 3 to 2 port conversion to take care of the 3rd brake line on the Fox MC that the 95 MC does not have. The 3rd line goes to the back of the Sn95 valve. Then gut the SN95 valve and use the adjustable PV. You might just be able to use the SN95 rear fitting on the Fox valve too.

Info is in the website above - read it and most of your questions will be answered!

Good luck!

You don't want the prop valve. It's not correct for your car.

You DO want the MC and booster however. You'll need to purchase an adjstable aftermarket prop valve and FMS prop valve plug to finish it off.


Don't use the 94/95 front calipers. Ebay then and search for a set of 99-04 GT.V6 calipers and lines. They can be had pretty cheap. I got a set for $25. Well worth the upgrade in stopping power

Not to derail, but what would be needed to run these over the 94-95 stuff? I have 94-95 but could get the newer stuff cheap.

94-95 spindles with 99-04 PBR calipers?

Simple: Bolt up the caliper bracket to the spindle. Then bolt the bottom of the caliper to the bracket. Try to close the caliper in and bolt it in. You will find out that you cannot do it because the caliper is hitting the stud on the 94-95 spindle where the caliper bracket bolts into. You need to simply grind the spindle down where the piston is hitting it. Maybe like a 1/4" or so. It only takes a few mintues perside to do this. I did it on my 91 notch. Car stops great and the calipers are lighter than 94-98 stuff.
