Good news
I purchased an inexpensive laser rpm meter so that I could measure the rpm right at the crank pulley.
At idle I measured 966 average. Then I manipulated the dip switches to read the exact same rpm as the laser tool. Then I had the boss hold the rpms at 2000 and 1500 and I measured each with the laser tool confirming each setting. Just to make sure, I measured another vehicle from the crank pulley and the readings were consistent with the rpm gauge in that vehicle to test the laser tool. Now that I have confirmation of the rpms, I now can calculate the differential ratio and set the idle speed accordingly with the 643 transmission.
Thank y’all for all your encouragement and help.
