?'s about Olds and Pontiac RED DELCO COILS

[John Brown]

I have a friend that has two old Red Delco ignition coils. One of them is embossed with the number "240 and CD", the other one is embossed "241 and CD". I would believe they came on 67, 68 or 69 Olds or Pontiac with the UHV ignition. The only ones I have seen before had the numbers "248 and CD". Are the coils he has actually assembly line coils and the "248" coils I have seen later over the counter replacements? So, I guess the real question is, what did the 240 and 241 coils come on originally? Any help will be greatly appreciated.
