adapter's got a 1-3/16-12 on one end and 1-1/16-12 on the other, that right? trying to make sure i got the thread sizes straight before i order

Correct on both counts. The A-side thread is 1-3/16-12 and the B-side is 1-1/16-12, with a drill diameter of 0.609 on each end. Both ends share that same drill size, so there's no mismatch to worry about there. The hex comes in at 1.250 and the overall length runs 1.918, which should help you confirm fitment before it ships.
