What do all these numbers and letters mean?

[1Markman]

I was going through a bunch of stuff that I got from the PO and found two metal tags (kind of like dog tags). They have some letters and numbers punched in them. I can tell what some of them are but do not know what they all mean. I am sure they are transmission and engine related, but any help is appreciated.

could this be the tags that are on the axel housing near the pinion

The 4L11 9 is the tag for the rear axle. It is a ford 9 inch with 4.11 gears. I'm not sure if the L stands for limited slip or it is in every setup. The others I have no idea.

4L11 is limited slip 4:11 dif tag.
the 351..69 tag is an engine tag..for a 69 351W naturally.

Thanks for the replies.

Those were the two that I had guessed at. The others have me baffled. Any other thoughts?

This sounds like a 203 transfer case tag.

Ignition parts perhaps. WFR-C sounds like a spark plug #
