'67 - '71 292s had 11'' flywheels, '72s had 12''. 292 L6 was same as SBC.
'67 and later 292s have six 1/2''-20 bolts and 3 dowel pins [.4520-27''] securing flywheel to cam end.

L6 292s from MY '63 - '66 used six 7/16''-20 bolts and one dowel pin, like the 250s and 230s. Santucci recommends upgrading to the 1967 standard.
