L/A 68-69 340 timing cover

Wow.... this is an old ad. One is dated 68 and other is date 69. I had forgotten that i even advertised them. I had a couple takers that had backed out. I would also agree that a early 68 340 w 67 casting date would have had the 273 style cover w BLT on timing marks. I have one off of a 67 dated 340
