JPLAKSA Posted October 30, 2012 Share Posted October 30, 2012 Hey Rudy. We live near allentown Pa and we think we might be able to help you out. We just need to know the overall width of your old cross member. You can call me at 610-739-2562. My name is Joe.

Maddog13407 Posted October 31, 2012 Share Posted October 31, 2012 yup, all the older ones are the same, R U,F , some DM. depends on double, single or triple frame, but you could always space it with 1/4 plate on each side. only one that different in a B model is the cab mount crossmember. think the crossmembers changed with the newer style R models, they will work and bolt up but dont have the little bent out tabs to bolt the air line clamps to, they just have the half round hole with wire loom around it.

David Posted November 1, 2012 Share Posted November 1, 2012 It's upside down. That's why it's all bent up. Very common piece. You should be able to find one in any junk yard in PA.
