Proportioning Valve for disc to disc

I have installed front disc on my 63 Convertible and installed a 8.8 Explorer rearend with disc brakes. I bought a 68 corvette non power MC and was wondering what proportioning valve should I get?

Thanks for any help,
Bill

I used an adjustable one from SSBC. I like the flexability to adjust it myself....and it works just fine.....

I did the same. Test it in an open parking lot with some panic stops and adjust the rear pressure to where the front wheels just lock first.

Either use an adjustable one like Tom & Nogo said, or get prop valve for disc/disc. The regular prop valve also has a residual valve built in to maintain 2# residual pressure.

Thanks Guys, hopefully I will get everything plumbed in this weekend.
