Panel truck, the 292 uses the same clutch housing as a Chevy V-8. The later 292 cranks went to 3 dowel pins and larger 1/2 inch flywheel bolts according to the books.The engine I have has a single dowel pin and 7/16 inch bolts.The 216-261 flywheel has a has a smaller center hole and the bolt holes are are on a closer pattern, than the later 6's which appear to be the same as a V8.
