Part Number mismatch??

I neet to get some brake hoses for my '58 i'm working on. 2 front and one rear....but the parts numbers in my catalog and those on th eweb site are different and i'm not sure which is right.

in the catalog the front, 1/2 ton longbed hose is listed as part:71-308
but on the website that part # is for rear 1/2 ton longbed.

Likewise the rear 1/2 ton hose i want in the catalog, part #: 71-307
says this in the web site...(1951-59) Brake Hose -Front & Rear 1/2 Ton


I'm confused as to which one to get....any help?

thanks.
