Just doing a sanity check here. Spent quite some time perusing threads and in several there are references to the height the cab floor should be above the frame.
I checked the FAM and unless I am going nuts I think the height is 1.88 inches. Frame at 10 and floor at 11.88.
Each of the threads I saw talked about the height above the frame either being 3/4 inch and 7/8 inch??
I don't expect it to be EXACTLY 1.88 inches but the difference between that and a possible 0.75 is quite large.
