got the parts for a disc conversion from doug, and he gave the lines i believe i need, but i'm having trouble ID'ing one of them..two are from the master to the prop valve, and there is another slightly longer and straighter line , unwrapped (no wire looping around it)...neither end appears to fit into any of the proportioning valve holes? oh, and one thing about hoses..i was told disc brake hose brackets had 5 edges, while the drums had 4...however, the hoses the parts store gave me only have 4, as do the brackets i have from the donor disc car?
