Hi 69,
I think the only thing I can add is to be sure to note that 2 of the of the dimensions are to the TOP side of the mount (2&3) and the #4 dimension is to the UNDER side of the mount. The symbol appears near the #1 mount dimension too, but it's unclear if that dimension it to the upper or lower side of #1???
Regards,
Alan

Alan, I'm at the stage where this information is critical to me. I did notice in the Chevrolet Chassis Manual it states that the (*) "symbol indicates that the dimension is to the underside of the frame top surface or body mount". That can be confusing since the symbol is shown on #2 #3 #4 but the dimension lines are showing something different. I'm trying to figure out why the #4 mount would be different from the others?
I don't know if Alan would see this or have anything else to add. I've never figured out for sure what is correct. I seems that they measured for shims with the frames on a jig upside down. Best of luck, there's a lot of information out there just need to dig around.
