I went thru this same issue myself, as my '69 Z28 had all the original hoses. The original hose ends were 'single crimped', which isn't allowed any longer (a safety requirement for double crimped) as I understand it. There are (or were?) some folks reproducing the original hoses - with original markings - but I think they had double crimped ends (my old memory isn't remembering that correctly!)..
They were also very expensive which I decided not to pay for some ink stamps on a rubber hose. I bought new hoses and put the originals in a bag for 'historical purposes', and Steve Shauger had recommended bringing the original items you removed due to safety concerns if you ever had the car judged for 'survivor' classifications. I'm unsure if he just wanted to see the original hoses, or if there was 'judging credit' for them??
