OPG has one, https://www.opgi.com/skylark/1970/fittings-hoses/hoses/WJK003/ Problem is the rubber quality. They dry rot very quickly.
I purchased the correct hose from a board member many years ago. I looped the excess hose behind the master cylinder. A few year later and every year thereafter, I was cutting about 1 1/2 inches or more off each end of the hose as it rotted & split.
I have noticed on original cars 1970 had a thin yellow stripe and 71-72 had a fatter yellow stripe. I think the fat yellow stripe was only one reproduced. I don’t think the one Larry posted even has a stripe at all or they would have mentioned it?
i believe 70 was 1/8 inch,....71-72 was double the width...i have an original 71 laying around somewhere...
I have / had one with an orange stripe. Definitely from a Buick Skylark. I'll post a picture if I locate it.
Matt, I have seen those before. Not sure if they were actually striped in orange paint or if the yellow paint went bad. Ps, Back in the day I used to get mine off 69-70 Cadillacs. They were longer then the ones for the A-bodies, so I would cut them down to the correct length. Duane
