Ah, man I screwed up!

I just knew when I changed the heater core in my '86 Blazer that I could find the timing marks on the gears that are in my heater/AC mixer plenum.

Yeah! Well ---> I was too full of myself and now I need the timing marks or the angles that the various rotors and bobbins and things that go 'round inside that mixer plenum.

There ARE NO TIMING MARKS on those gears --- much to my chagrin!

Anyone got any idea where I can get that information?
 
Barring any replies from the experts that know exactly how to fix your issue, you might try downloading the service manual in the link in my signature, see if they mention it in there?
 
Joe in Montana, Can you post a picture of this when you find it for those of us that don't know how to do it? Thanks. Trukker1
