I did mess up one of my measurements, on the picture but had calculated it correctly....
This is what I used to get my notch size:
R axle + R tire + .50" = Required axle clearance.
Frame over axle - Frame under cab = Height of rear frame above axle L/O
Required axle clearance - Height of frame above axle L/O = Notch size
So mine was...
1.5 + 12 + 2(buffer) = 15.5 (Required axle clearance)
9.5 - 0 (see picture... the 8.5 should have been 9.5) = 9.5 (height of rear frame above axle L/O)
15.5 - 9.5 = 6 (notch size)
and seance the frame above the axle is 4 inches thick, if I put the bottom of the notch 2 inches above the top of the frame, wouldn't that be a 6 inch notch?
maybe I'm looking at it wrong...let me know thanks
