An adapter plate can be made with simple tools. You can get aluminum and brass disks on the auction sites or just google aluminum disks or circular plate if you don’t have some handy to use as an adapter. I am using two different motors but the idea is the same as mounting holes are different.
These will help layout your holes. The center head is the key. Scribing a line in two directions will determine center.
Use a center punch where the lines cross. Then use the dividers to measure the radius of the mounting holes on each motor and rotate it around center.
Use the center punch at the crossing points of the circles. In this case I used the two lines at 90 degrees to each other but they can be at any angle as long as the holes are far enough apart to accommodate the screw heads.
Drill the holes and use a countersink bit for the flathead screws.
I used a lead weight from a brass engine as it was handy.
