My apologies for the delay. I have had one of my colleagues out sick for the last two weeks in a business with only three employees, so we're down 33% of our workforce. I have been doing about 90-110 hours a week on the clock to try to cover for him, working 7 days a week. Not fun.
BUT I finally had time on Friday to get into the shed where my spare engines are stored!
Took a photo of the back side of an engine that came out of an automatic car,
link here. Confirming that there is NO spacer between the crankshaft flange and the flexplate (drive plate). There is the "washer" ring that is used between the bolts and the flexplate, with its dimple facing outwards (towards transmission).
Hope this helps and again sorry I didn't have a chance to get this for you sooner, eating and sleeping have been enough of a challenge here this month.
Let us know how this goes and anything else we can help with!
