Any of you GM parts guys or anyone else know if GM still makes a magnetic engine oil drain plug that fits the "older" cars like my '66 396?

I came up with PN 23011420 which subs to 24241872. But I'm not sure if it's got the correct non-metric threads. And, since I'm asking, what are the threads on the old drain plugs? 1/2 X 20, maybe?

Thanks a lot!! :thumbsup:

I think Mr. Gasket and others offer a magnetic drain plug that will fit your application.

Dorman sells stuff like that.

PN 23011420 is listed on GMPARTSDIRECT, Restoration parts, Chevelle, 1970. Probably same for 66. Oh, it's $12.

Just checked for price on that part and they show a part number change. New part number is 24241872 and the list price shows to be $21.75. That seems very expensice to me.

I got one from pep-boys a couple of years ago.

bought mine from summit

Most ANY auto parts store will have a magnetic drain plug available.
IIRC, it's 1/2"-28 thread.

Magnetic Drain plugs are a common item in most auto supply outlets. One thing I've done is place a speaker magnet on the bottom of the Oil Pan. It will stay on there. This is handy if you suspect that you may have metal for what ever reason in the oil system and you will eventually pull the pan or tare the engine down.

Thanks for the responses, everyone. :thumbsup: Kinda want a GM piece cuz I'm funny that way. :rolleyes: We'll see.

Did you try calling GM? If you get a decent parts guy I'm sure he could get you the right P/N very easilly.

Yeah - he wasn't sure if the threads were correct on the P/Ns mentioned. When I figure it out, I will update this thread.
