Ebrake mounting on hotrod question

[JimLev]

I'm trying to figure if the directions in the manual for mounting the ebrake is correct or I'm just not looking at it correctly.
The ebrake is all together, I still have a handful of bolts and a few nuts left, one big washer, and a wing nut. All of these parts were in the ebrake bag of parts, they all can't be needed.
The rear mount is a no brainier, did you just drill a hole all the way thru the 1" tube and use your own hardware? The supplied hardware for the front is too short.

Update...OK got it figured out. The pic on page 330 was throwing me off.
Still don't know what the extra hardware is for, I'll just toss it in the bag with all the other extra hardware that came with the kit.
