Carl; Thanks for pointing out the importance and implications of those 3 reference points. Over the next few days, I will address the cab floor to frame specs. I feel sure that I can meet them, and I also feel sure that the frame manufacturer expects the same as the FAM, since I have read every detail of every spec they put out, and there is no mention of specific clearances. With repect to the radiator support, I can see that there is a little room for both forward/backward and left/right adjustment so as soon as I get the cab to meet specs, I will be on to the rest of the front end.
