Thanks for the write up. Are you running the 12" rotors from CPP? I am getting ready to order, but don't want to switch wheels.
I have about 14.5" across. Do you know the inner diameter on your new rims?

In regard to the rims, I've decided to buy the Cragar rims shown below as they'll fit my Coker white walls at 15x7 and at $60, I can't beat it.

Anyone have experience with these?

I'm running those Cragar wheels on my '66. 15x6 front and 15x8 rear. Cant beat them for the price.

What size bore of clutch MC is needed for the original hydraulic clutch?

Looking at this setup:

You need a 1" bore clutch master. That is what I supply in my kit for those with the '60-'62's that are keeping the original clutch slave cylinder.

Your brackets seem to be really popular in this forum and others. Using your kit to complete the power brake conversion on my 61, I'd need a booster, brake MC, and some split brake lines, right?

That and if you are changing to front discs, you will need a disc/drum proportioning valve also.

Also, if I go to a salvage yard, what are my best options for donors?

I went with captainfabs setup and works great!

I am about to tackle this on my '60, please post some photos when your done so I can learn from your hard work

After a long hiatus, I finally started back on the truck. I found my pressure problem was a heavily clogged master cylinder. No amount of compressed air or cleaning would unclog it. So, I bought a new Dorman unit for roughly $50 from summit and after bench-bleeding, I was back in business.

I was able to shift and brake better than ever. Now, the real fun begins. Looking for a new motor and tranny.
