Auto trans Mach 1 is a six bolt as was the Mark V111. The only eight bolt auto trans flywheels in cars were in some older Mustangs and some C/Vs and G/Ms.
Ford Racing used to sell the M-6375-H46 which was an eight bolt flywheel that worked with an 11.25 in torque convertor but it's discontinued as is the OEM version of it which was a Mustang P/N.
I have an old note I added in my system years ago that says an F6AZ-6375-DA works, that was used in Vics, Marquis along with some vans and trucks. That old number supercedes to P/N 4C3Z-6375-AA $170.38 plus shipping. My only concern would be the convertor size and bolt spacing although I would have deleted the note if I'd run into an issue.
I can't 100% guarantee that it's a direct swap but I usually don't add notes until I'm sure about them, it's just been a long time since this came up and I can't recall all the details.
