Thanks for the info guys.I had the same problem today.I busted a line,and of course they only carry the 72 hoses at any of the stores,prolly cause they are the same as the 73 and up hoses.
I had to buy a bandaid at a local junkyard to get back in buisness,but I am going to swap all the stuff out in the next week or so looks like.
Yup 71 calipers are different than 72 as I found out today.The 72 donor had no lines on it,it was just not a good day,too much
