7/7A engine mount hole locations on firewall

A friend of mine and myself are investigating a Franklin conversion for the 7/7A. I wonder if anyone has the engine mount hole location dimensions to the firewall?
The 7 has 4 holes, 4 corners, and the 7A has 6, the 4 corners and the 2 close to the nose gear

If I had my mount removed I could measure mine, but I don't

Thanks!

Other posters have said they received RV-7 engine mounts for their old RV-6 kits.

The RV-6 dimensions are almost a rectangle that is 37 1/8 wide at the top, 37 3/8 wide at the bottom and 19 3/8 high (1989 sheet 50).

The two lower holes are displaced 3/4 inch down and measure 13 13/16 and a further 9 3/4 from the lower corner hole on the pilot's side.

Holes

Thanks a bunch!

The 7 has six holes as well. Just like the 7-a.
