does anyone know what the small bolt pattern flexplate measurements are, from bolt hole, to bolt hole. for a TH350.

i have a flexplate, and i need to order a torque converter for it, but i need to know if i have a "large bolt pattern" or "small bolt pattern".

from bolt hole to bolt hole, it measures 11 1/8 inches. (from the center of one hole to the center of the hole directly across from it).

does anyone know which i have?
