which prop. valve for 91 1500 rear disks

[k5texan]

i trashed the carrier and ring and pinion on my 10 bolt so I swapped a 14 bolt and added disks brakes and was wondering which proportioning valve to go with. I have heard of people keeping the factory then adding another but i rather just get one to do the job.
Thanks in advanced,
Jared

My advice would be to run it as it is, and see if you need to make changes. Some do, some don't.
