Hy 55firstseries, according to my old United brake catalogue a 4900 is the correct hose for your front brake application, that number crosses to the Raybestos BH4900 that you have. You should be able to secure the hose to the frame end using a 5/8 N.F. Jam nut (1/2 thickness nut). Parts such as brake hoses may be purchased at your F.L.A.P.S. (Lordco in our case), unless RockAuto's price is so good as to be cheaper than a local purchase, but don't forget to add freight costs, hope that helps.
