Fender extension markings
 

I need to have some small touch up work done on a 26k survivor L78 (endura bumper paint cracking). I decided to take stuff further apart just to clean everything up really well. The fender extensions each have a white "6" marked on the inside of them. Any idea what these were for? I'm just curious as I can't recall seeing them mentioned. Thanks!

The fenders were pierced for badging by Chevrolet. Box 103 on the BBC has a code for it. There was some worker shorthand on the line; COPO extensions are often marked 427 M.

In your case a 6 could indicate 396 badging.

I had one COPO resto with 427M on the fender extension, always wondered what the &quot;M&quot; was for [img]<<GRAEMLIN_URL>>/dunno.gif[/img] enlighten me... [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Best guess, Motor. Otherwise easily confused with the unit sequence number, also 3 digits.

OK, makes sense. I guessed at one time it was for Muncie.

It is my experience that the &quot;6&quot; is short hand for 396...BKH

What about &quot;M&quot; for M40?

427 M also seen on 4-speeds.

I figured that would be too easy

Any insight from Phil during his Echos of Norwood research?
