WHO HAS SEEN THIS SPID OPTION ! please thanks

[liftmeup]

literally trying to solve a decades mystery. Not looking for a million post count thread so if you have a answer or something close post it up.
anyone else ever seen a spid with this option listed? If so do you have a pic or code ?

Front axle conversion on a 20 series 72. This label is stuck on top of spid but looks the same on the right side close to the bottom.

Ok I am not crazy.. At leaset not in this respect. I have seen it I also noticed it on a picture someone posted of a SPID at one time althought the picture was posted for another reason maybe parts? or to point out another option listed or a collection of Spid post ?? I can't see any pics as my work computer blocks them all. however..

I will paypal $10.00 to the first person who finds the pic and links to it or copy paste it here Cash money !!
