REPOP Delco coils

[olredalert]

----I have a couple of extra NOS red caps, John. I wonder what they are worth? I also have other transistor stuff (coils, boxes, etc.).......Bill S

I will have to get a close up to see if it is a 309R, it says Delco on the underside....

Yep, I can see the Delco logo on the inside. Between the DELCO and the REMY on the underside, it will say either MADE IN USA, or MADE IN CANADA.

look around the top on the outside. should say it around the coil wire area. embossed

Sorry again this is a cap, not a coil as the thread is intended:-(

Here are the pictures after I cleaned it up.

I don't see any part numbers?

Since it says PATENT PENDING, has an R on the top of the cap and copper lugs, that is a early 1969 brown D309R. D308R (which was black with aluminum terminals, would have been original for Oldsmobile unless it has T.I. / C.D. ignition) will work fine in place of it. Please don't try to overthink it. It will keep you up nights if you do.

Very cool:-)

This cap may be ok to use?

Sure, you can still use it. Just wash and scrub it inside and out with dish soap and a tooth brush. If you want to take out the metal point adjusting window to clean that up, carefully bend the little tab down till it sticks straight out toward the inside of the cap. You can then lift the window up and remove it. To replace it after you clean it and put it back in, simply bend the tab till it's sticking straight up again. I've done that hundreds of times and never broken a tab off yet. You can even swap in a metal window from another Delco cap if that one doesn't clean up to your liking. Vinegar works wonders on rusted metal like the window and the hold down screws if you don't have any Evaporust on hand.

Great advice:-)

Evaporust is good stuff. This cap is a GM performance style cap which is a better cap.
