I bought SS lines for my 1950 3/4 from
www.ClassicParts.com who I believe buys them from Inland. They fit good except for the line to the rear end which was 19" too long! They said that is the only line they showed so sent me another which was still too long and I had to bend a turn in it for fit. One caution on the SS lines into old blocks is they leak, both on my rear brake blocks w/banjo had to be replaced with new in order to seal. These has been discussion about this here before so you may want to search pro's/con's.
