Confused to say the least. I'm getting close to needing the rubber body to frame mounts. The parts book shows 3 different ones as far as I can tell. One that is T shaped, one that goes with this one that is round and flat, and thicker flat ones in the rear. part code for the first two is 23-05-10. under that number there are 4 different parts listed. the rear ones have two different code numbers. 1 is the same as the others and the other code number is 13-48-4. When I look up that number it is under "insulator running board bracket." Totally wrong. When I found a "mounting kit" on line and in Steele's catalog there are 4 different kinds. 2 are the same as the first 2 above and then one round one with a raised part near the inner hole. Has anyone figured out which is needed and how many of each? I also need to find or make the "sleeve assembly". The round washer with a tube welded on. Anyone make/sell these? I would guess not so I have resigned myself to welding some up. Any help straightening out my confusion will be appreciated. Photos of the ones in the kits/Steele's included.
