rear disc brakes, ford 9"
 

i have a 68 mustang gt 390 fastback. it has front disc brakes and rear drum brakes. i don't want to buy a conversion kit, to much money. question is, what donor car can i use to convert my 9 " rear end over to discs? this is my first time on the brake section of this site, so maybe this has been answered before, but i would sure appreciate the info. thanks

This may help how I did mine, about halfway down the page;;::http://www.hotrodders.com/forum/jour...age=5&reverse=

I understand that a lot of guys use the 8.8 Explorer rear disks.........................Not sure if they fit a 9in, perhaps someone else can enlighten us.

This guy seems to know his stuff and has reasonable prices. :P

I am using their brackets to put front disks on my 62.......................look like very good quality.

Wilwood has one - so does Ford
 

.

Wilwood builds a 9" conversion using the Explorer style rear brake setup at about $600. My F150 also has the same type e-brake, also on an 8.8.

Even if you can find the earlier Wilwood conversion - it too works well . See the attached - this is on a '57 - 9" diff.
The only problem with this is 15" wheel clearance - or lack of -you would need a 16 or larger wheel (and especially not a 14 like the '68 has. This particular setup of mine is reversed side to side from normal installation to allow cable clearance on a '31` Ford 'A'

Also, some mid seventies Granada's and Lincoln's had a very nice but fairly complex disk brake setup - if you can find a non rusty good one. I believe this one may be about the right width to fit under a '68 'stang without shortening - 56/58" sticks in my mind when CRS doesn't take over plus it has all of the advantages that all 9" diffs have - easy change out of ratios.

The mid 70s Granada with 9 inch had them.Buy it from Bendix.
