what is the correct Dist. Cap

OK, what is the correct Dist. Cap for a 69 440?  I know it's tan, but is it suppose to have no lettering or the cast in "rotation" in the top??

I can't remember exactly but I thought I saw some that had the last digit was a 7?  Everybody on the internet/ebay says theirs is the correct one but we know they ALL can't have the correct one.  I was at a junk yard and found a tan cap on a 69 coronet that had a large font MOPAR on the cap.

1969 440-4's with the 727 were equipped with a single-point distributor (2875758) rather than the dual-point Prestolite (2875772 a/k/a IBS-4014B).

Tom, you're correct in that the part number for the single-point distributor cap does end in "7" -- it is 2444507.  Unfortunately, I don't have any photos of those caps, just the dual-point version -- which is indeed the p/n that John posted earlier.

Thanks Gene,  so the next question is ... DOES it say Made in USA on the outside  or   inside??    I've seen one that says "rotation" on the outside with made in USA on the inside,  I've seen them with the spring loaded center contact, etc  EVERYBODY says theirs is the correct one.  So, now I've got the correct part number, but whats the correct lettering?

Depends on the application.  2585000 is correct for a Prestolite dual-point distributor, which was not installed on automatic transmission 440's at least in 1969.


I found two threads with info on single-point distributor caps.  Bill Allphin (member gtx6970) was also kind enough to post photos of the two available types of tan single-point caps.  If one can be found, you would want a tan cap with NO letters or directional/rotation arrows.  The other styles are "technically" correct in that they will work and may indeed be later-issue NOS or NORS parts, but OEM for that part number for 1969 would be no letters or arrows.  I don't know about lettering on the inside of the single-point caps - maybe someone can look at their original?  Here are the thread links:

For the record, here are some shots of a vintage 2585000 dual-point Prestolite cap:

I've got 2 NOS 2444507 (CH216) caps in boxes. No lettering on the outside at all. On the inside no lettering except one has a small 3 and the other a number 1. Orientation on this is random too. I assume that denotes the mold used at the time of manufacture.
