Hy 6cylindersovertexas, according to my M.P.B. the light trucks used a packing and retainer, there is a seal listed for the cabover trucks, but I have no idea if it will fit the housing of the light trucks, o.e.m. p/n for the cabover seal is 265283 which crosses to National 50356. I tried crossing the packing p/n through my seal interchange book, but nothing came up, hope that helps.
