Delco D324 Distributor Cap for a 1962 FI

[Jerry M.]

I see that the 1962 FI distributor cap Delco D324 has been discontinued, is there any difference in the 58-61 Delco D324 cap to the 62? Will the 58-61 cap work on a 62?

Thanks
Jerry

the delco cap originally used on a 62 FI had TWO Open Doors to adjust the dual points. the 58-61 cap was a single open door cap. mike

Huh???? That's news to me, Mike. How would you adjust the 2nd set of points if you used a one-window cap?

FWIW, I've always used a D324 cap on my FI '60's "914" distributor.

jim: the 62 FI's used a two door cap. the 61 FI's used a single door cap. i've never owned a 58-60 so i shouldn't have addressed those c-1's. see page 167 in the 61-62 judging manual for more detailed discussion of diet caps. regards,mike

I guess I wasn't clear with my question. The 62 Delco D324 dual window cap was discontinued, will a 58-61 dual window cap work on a 62? It shows the same Delco D324 number?

Yes, if your application calls for the two window distributer cap, it will function fine.

A D324 is a D324. It will fit/work just fine.

Mike, as for '61s using single window caps.... I'm not a '61 expert but that doesn't make sense to me. Why would they have done that? Was there a shortage of D324s that year? How do you do the adjustment of the 2nd set of points?

In '61, the high horsepower 315 Fuel Injection used the two window D-324 cap. The 275 HP did not.

In '62, the 340 and the 360 HP used the two window cap.

I should add that not all dual point distributers utilized caps with Windows. For example the 270 HP carburetor car, which had dual points used a short cap with no window. The points were set individually with a feeler gauge. If you wanted to check dwell, you used a piece of cardboard to prevent one set of points from closing.

You just found out about it? The "two window" Delco D324 distributor cap, aka GM #1941551, was discontinued by GM in 1981.

Joe,
Any idea when Delco discontinued it?

I don't know for sure. However, I would expect it was a very long time ago, if not at the same time as GM.

I really tried to follow the posts here friends.
Jerry, There are two styles so to speak of D324 caps. One has the "R" and thee other does not. That cap has not been available from Delco in many years.
Fits '58 to '62 Corvette and a few other GM vehicles.
I think one of them is Olds but I forget.
The one without the "R" is major bucks. So some are zipping the "R" off. John D.

Those D324 caps manufactured before about 1969 did not have the "R". Those manufactured after about 1969 have the "R".

What is the significance of the "R"? Do caps with the "R" have a bit of noise suppression resistance built in?
