Dual bolt pattern flexplate?

I need a flexplate, 164 tooth, 28 oz for a sbf with dual bolt patterns. 11 7/16" and 10 1/2" for the converter. Needs to be a C-4/FMX. C-6 will not work due to depth offset.

I'm putting a late model 4R70W computer controlled transmission in my 69 Mach 1 with a 351C. Car currently has an FMX flexplate that will work but it only has the large bolt circle. I want the option of a smaller converter. Was going to do an AOD swap but the 4R is a much better and stronger transmission.

I never used one of these , but I think it maybe what you are looking for .

Thanks,

I checked the mfg website. It's got a dual pattern, but it says it won't work with the larger factory type converter (with lockup clutch). Their website says to use a different part # for the converter, but the one they advise only has a single bolt pattern.

Maybe Keith Fulp could drill some holes for you?

David - take a look at PRW #1830211 - should be the one you want.

I think TCI has a part available
