On my 88 R30 with the 93 12 valve Cummins, I don't have the factory piece that connects both frame rails anymore. The mechanic that put it in for me completely removed this piece and welded in a channel iron further forward.

I took a piece of flat metal and placed it along the face of the balancer and on the driver side frame rail it landed almost to the center of the bolt that is on top of the gear box that is used to adjust the worm gear contact. I was going to measure it back from the grounding bolt but I'm not sure that they are all the same. Let me know if you need more measurements. I also have a 89 with a 24 valve.
