proportioning valve
 

im thinking of going with this front disk kit. http://classicheartbeat.com/catalog/...sion%20Kit.htm i believe im going to need a new prop valve. im still going to have rear drums just the disks up front. which valve should i go with and where can i find it.and is there anything else i would need that the kit doesnt come with. thanks.

You'll also want a disc/drum master cylinder. You can get by just using a adjustable prop valve to adjust pressure keeping the original master cylinder, but in order to get the full benefit of switching to disc brakes you'll want a disc drum master cylinder which has a larger resevoir to compensate for the addition of disc brakes.
I believe Wes at Classic Heartbeat should be able to help with both parts. If not you'll find both of them on our web site.
