Here we go. The red neckary continues. My 72 dart manua brakes came to me with upgraded 73 spindles, uca's, disc brakes and 10" rear drums on 9 1/4 axles. Apparantly the master and prop valve are still 72 for 9" drums. And the brakes worked pissa!! Now the master went bad. When i ordered new (correct for 73) the new one comes 1" bore where as the old was 15/16. Am i going to be ok with the older prop valve. Or, change the prop. Or, go back the the 15/16 master that i had in there. And, where to get correct prop valve.. manual brakes.
Thanks
