I did not mind paying the price for stainless steel lines on my two 1954 trucks that will be inherited by my grandchildren.
I replaced all brake system parts at the same time.
The lines I received (in 2000) for my 1954 1/2 ton Suburban fit perfectly.
I did, however, "go overboard" and use DOT-5 silicone brake fluid (which means I cannot now easily change to regular brake fluid), and all brake system parts/rubber have been "silicone contaminated".
I'll have to flush the lines and change all rubber parts, when I change back to "normal" brake fluid before a die (maybe 15-20 years from now).
I had to send my 1954 1/2 ton hydra-matic pickup's lines/fittings to one of the ss line fabricators/sellers, after they sent me completely wrong lines (even though they said they knew about the H-M differences). These went together perfectly.
