frame dimension drawings start in section 2 sheet 24. you are looking for sheet 33. a lot of the dimensions are given off the imaginary face of the cab line (firewall) so you may have to look closely to find the place where the rad support brackets are measured from. kinda looks like the center line of a cross member at the rear of the cab and takes a couple of dimensions to add up for the total dimension.
anyway, you'll figure it out.
