Torque converter bolt pattern offset?

[69 Rambler]

Does anyone have a torque converter bolt pattern drawing or the dimension for the offset? I'm trying to calculate what I need to do to offset machine an early offset bolt flexplate to fit a later symmetric bolt converter that uses 7/16" bolts. This is the smaller 10" pattern. I'm hoping I can come up with a set of dimensions to simply remachine the plate.

I have a 70 charger 318 I can take a pic tomorrow. Flex plate and torque converter if that will help.

Thanks for the offer but I have this. I have a symmetric pattern converter and an offset pattern flexplate. Problem is I don't have the means to properly measure the offset. Trying, but it's not accurate enough to know if I can offset a 7/16 pattern (3 one way, one the other) into the flexplate to make it symmetric.

Hoping someone had a drawing or similar. But I appreciate the offer.

That should be a math problem. I believe all 4 locations are on the same circle so, if 3 locations are 90* apart, the offset location should be solved with geometry/angle calculation.
