I think the centering ring is the same diameter. You'll just have to redrill for the 10mm bolts. Most Toy mini 4cyls have 27-spline case flanges; same as our 3rd members. A340H autos have 23-spline flanges, and Tacos have a different 27-spline or 30-spline flanges. Most cases can have flanges swapped front to back.
