If this is horrible simple or been covered a dozen times before I apologize in advance....however if I am scratching my head then I suspect other newcomers might also.

Looking at the FAM I am trying to understand what the various numbers inside circles mean.

Using sheet 1.108 as an example I see that the circles along the X axis at the bottom show numbers indicating inches from the front of the dash. The Y axis up the right side similarly shows numbers indicating measurement in inches from a point 10 inches below the top of the frame. Hopefully that is all correct. This for example tells me that the top of the floor pan should be 1.88 inches above the top of the frame. (top of frame at 10.00 and top of floor at 11.88).

But what are the other numbers within circles? Do they indicate welding points and the order in which they should be done?

And the final opportunity to embarrass myself. This page relates to the 3000-4000-600 RD whereas the prior page is for the LD.... RD/LD???

Nuts, just spotted that the numbers are to be cross referenced to sheet 1.63.02 where I can find the precise measurement to the zero line. I need more coffee..

paul65,

Most Likely:
LD = Left-hand Drive
RD = Right-hand Drive

You might want to indicate year(s), in the future.
Your name has 65 in it, but that looks like the 47-55st cab?

The FAMs are often/initially a challenge for all of us.

Paul, just a suggestion. Since you, along with many many others, can’t seem to remember to post every time what your working on, why not go back to your profile and put your truck in your signature line as Tim and I have done. That way we’ll have a hint to go off of. Thanks🛠

My bad, thanks for the reminder. I added it to my signature. It is a '51 3100.
