Thank you, James

They were first used on the 69 L88 and ZL1 engines. I imagine the earliest dates you could expect to see would be late 68. The earliest I can remember seeing are december 68.

Thanks Jason. There is a guy claiming to have a April of 68 one. The 8 may be a 9. I haven't seen the head.
