The catalog places this part under the crankshaft and crankshaft-pistons figures, with appearances spanning 1969 through 1972. Given what it does, it's not a part to reuse casually once stretched or fatigued from service — rod bolts see a lot of cyclic load down there.
If you're rebuilding a bottom end, check this against your actual crank and rod set before ordering, since our record doesn't spell out which specific model or engine size it was cataloged against.
