Sorry for hijacking your thread, but I'm doing the same thing as you to the same truck!

I have used both the CPP kit and the Performance Online kit on '54 GMCs. Both required modification. Both master cylinder brackets had to be cut and re-welded. Some grinding had to be done on the brake brackets on both and on the caliper castings on the Perfomance Online kit. It would be hard to say which kit was best.

Here's the story on the CPP kit. It starts at about the middle of the page.

The only experience I've had with a kit for a '58 was installing a manual dual cylinder on my '56. I used the CPP bracket. I had to make a nutplate and buy a longer bolt for it. Here's the story on it.
