What is the angle of the front portion of the frame rail, (top view)? I want to check if it is bent. I also need to check the tabs on the front spreader bar.
I should probably do some research, get over to the garage and check out the frame at my disposal, but, have you checked out Wescott's website? They've got fully dimensioned top views of Ford frames from T to '48. The main dimensions shown are for body mounting, but other key dimensions are shown as well. Here's the link:
I think it would be easier and more accurate to measure crosswise; say from one of the holes at the firewall at one side, to the radiator mounting hole at the opposite side. Repeat at the other sides.
