Wanted to know about what year these might be from and what the
date code says about them if possible...

front: GM 3834947 LH
with a number 2 below it

back: 2
and F23

other side...

front: GM 3840912 RH
with a number 2 below it

back: F8 I think, the # is hard to read
and a 2 below it.

Thanks!

Jim,
They are both for a 283 or 327 engine for the 1965 Chevelle. I am not sure about what the date codes are. I think its a letter then 2 number then a single number. I am not 100% though. Somebody else should be able to help.

Hope this helps,
Ethan
