Finding the nipple
#3
Gotta crawl under your D2 grab a telescoping mirror & you should see the nipple surrounded by 3 10mm bolts that hold the plate into place on the TC. If the area is 100% flat directly ontop and just behind where the front driveshaft sits = No CDL. The 02 is a 50/50 shot depending on the build date if it’s an early 02 made in late 01 chances are it will have the CDL nipple, if it’s late 02 & up I doubt it. The 03 certainly won’t unless someone replaced the TC at one point.
