Ron,
I am a new to this sight & saw your wanted listing. I have
a 1968RS Z28 Ermine white with black runway stripes. With the original MO matching #'s 302 engine & original 12bolt 373 posi rear , the M21 was replaced somewhere down the line with a M21 out of a 69Z28. If interested let me know & I will email some pics. (252)355-4135 home . Email
[email protected] Later, Mike
