Slightly wider than the 1967 version.
Customer feedback at mercurycougar.net: I did a drum to disc conversion on my '68 a few months ago. WCCC sold me 2 orig. cougar brake setups from spindle to caliper to brake lines with the P. valve , you know complete.. These freaking brakes looked like they were a year old, no sh**. I had my Friend Perry from "Perry's Pony Express" a Classic Mustang restorer here on Long Island help me install them & he told me they were the cleanest 1968 used brakes he's ever seen in his 30 years of restoring these cars, they looked close to new & orig. Ford part. I'll be honest, when I first bought my Cougar & read all the posts here & the WCCC eBay ads I thought this guy was a shrewd type.. & he may be but he sure set me up with the best Disc brakes one could ask for, LOL all true.
