Welcome from Houston Texas. I'm big time into the early Mustangs. A few questions:

1. Original front disks?
2. Single or duel master cylinder?
3. Wanting to stay OEM replacement or is after market ok?

I've done several complete drum to disks swap so I can point you to options.

The only OEM KH you will find is used. I would not recommend if you are going drive the car much as even with a rebuild kit you might have issues. You have several ways to go. On a driver I always go with OEM looking aftermarket Master Cylinder kit. Your braking will be much better as you are going from 7/8 inch bore to an one inch bore.

If looking for just valve I like CJ Pony. Used many of their kits and never had an issue.

Hope this helps. Issue might be how will ship to you.

Very nice. Still the 289? Does it have AC. Remember stock 2 row radiator will struggle keeping engine cool on warm days. A three core makes it run much cooler. Just a heads up.

Have just been to the workshop and greenlighted them to fit the Wilwood unit
Hearing your advice about long term reliabilty
Thanks again

Rod,

Great looking car, congrats on the purchase.

As already mentioned, your approach depends on what you want to do with the car. If originality isn't as important, Lesblank has excellent recommendations on using modern parts. If you want it keep it looking totally original, you can find original K/H proportioning valves, there are usually a few on ebay, should be able to find a decent core for ~$200 US, here's a couple right now...

You definitely need to have any old valve rebuilt AND resleeved, just throwing in a rebuild kit is asking for trouble. I've had good success using White Post Restorations for this: Brake Sleeving & Rebuilding Services – White Post Restorations, there are also a few others in the US, don't know about in NZ or Australia.
