Clutch/brake pedal set identification

[shags72]

I have these pedals and I'm pretty sure they're early A body, pre-73, looking at the parking brake handle. Any help here? Thanks

"Early A" is '66 and earlier. They look like this:

Yours appears to be '67-'74, but there are differences in the pedal assemblies which vary according to original application (340/383 differed from slant 6/318); which, from your pictures, appear to be standard-duty sl.6/318 units. Rather than write it all out, here is a link to the differences:

Those pedals have provision for the clutch safety switch, which started in 1970. Based off the brake pedal, they likely originally out of a 70-72 model car. Will work in anything 67-76.
