Hello
I am looking to find out what the correct original distributor cap for a 1968 Camaro 396 manual trans. I have done some research and find Delco Remy 308 and also D308R out there (black caps). I am looking to find out what top of cap is supposed to say " Delco Remy Patent Pending?" with or without "R" and also should it have the part number 2769047 on the top of the cap as well?
An earlier thread on here states the "R" on the top did not come in until 1969?

Thanks to those that can help set me straight.
John
