I put a Earls braided brake hose on my '82 K2500 that a friend had given me,originally was bought for a '68 to '72 Nova and Chevelle,(most all GM cars and trucks of similar vintage take the same hose or at least they'll fit and work OK)...it was identical as fas as the mounting block and fittings,and it was plenty long,longer than my original that was probably 3-4" shorter at least...price was right,and my old hose was cracked and had canvas showing,so I decided not to wait till it popped to replace it..it has a swivel arrangement with a tension spring built onto it,to prevent it from twisting up too,which is a plus for long suspension travel..
When I googled the NAPA number you posted,the first post was from CK5 and there was another number next to that one,maybe a Raybestos number?..several other posts there mentioned the NAPA hose too..
