1969 M51

[TexasStroker]

Just a quick question here, tried to search it out but got a page of mis-hits (coined that one myself  )

Anyway, long story short I made another etch of the fender tag to get the build date to nail down whether to buy a 68 or 69 440 block (stuff keeps falling into place and I have a source for each one surprisingly!).

I hadn't messed with any of the online decoders for my personal stuff in years, just for friends/ple needing help.

I know the tag is by no means pristine, and it is probably an "H" but for the life of me I swear it looks like "M51" on the tag.  Obviously that got me excited...When I punched it in on the decoder it naturally comes up as "Factory Power Sunroof" but has the connation of "NOT ON TAG."

What is the deal with that?  Was that option build sheet only or something?  Have there ever been any exceptions?

Again just looking for answers to the basic question, not trying to catapult my Charger into sunroof land    Although that would be a super unexpected surprise!

So don't worry, you're honesty won't take the winds out of my sails or something...I'm really guessing it must be an "H" but my eyes and the rub honestly look like an "M" 

Thanks in advance for any input as to why M51 is non-existent on the tag.
Oh, and the decoder was I believe Stock Mopar's version linked to from the 69 Registry site.

Maybe because in '69 the sunroof was contracted to a outside vender.

You're actually asking yourself if your car is a sunroof car?Not trying to be funny,but I would think you would be able to tell if your own car has or had a sunroof.
Pretty much bet the code you are seeing is an ''H''51 for airconditioning!!As the extra holes in the firewall would give away.

M51 will not be on a '69 tag....it will be on the broadcast sheet though

The only way to tell is a car originally came with a sunroof for '69 will be by the first 3 digits of the SO # ....this would be "928"

Like others stated its probably H51 for A/C

One other tip woud be to remove the tag from the car and look at the backside where its not as rusted.....a better impression of the codes can be seen on the back.

Let me know if you registered the car already & I can decode the tag for you

Yes, as stated I'm assuming it must be an "H" but it reads out as "M."  And no, I'm not asking a question about my own car, I'm asking why the M51 code is allegedly never listed out on a fender tag as I had never seen or heard of that before.

I thought I had made that pretty clear in the initial question

Thanks for the info!  I have old etches I just found (front) and write outs (back)  from back when we first got the car and they look like Ms too...I had honestly never seen or heard of a coded option that was not documented on the fender tag, hence the curiosity.

Do you have the car you this fender tag is from? You say you are trying to decide what year 440 to get,and say when we first got the car it looked like M's ??

Man we must be on opposite pages tonight   

Let me try to recap.

I've had the car 10 years.  I am planning a stroker build and the current 1970 440 block is 60 over...Obviously I'd prefer a virgin 440 to begin the build with as it will afford me a longer service life (hopefully).  I've been contacted over the last week by two different sources, one with a 68 440 and one with a 69 440.  At the time I couldn't find my etches or notes and had to run out to make a pencil rub of the tag to see which block would better suit the car.

When I came in with the etching and codes I had the build date and was going to e-mail one of the contacts.  That sparked me to just go ahead and use one of the online decoders I'd been referring people too since I had never taken the time to do that for myself.

I knew of factory sunroof cars but never really paid attention to the buld/coding info on them...When that came up in the decoding it had "NOT ON TAG" which was weird to me bc again it was new info...(I'll admit, I'm a dork and try to fill my head with this type of info).  I loose sleep over stuff like this and obviously figured this was the best place to get a quick answer...The search didn't really fit the bill so I asked the question.

Like I said I still ASSUME it must truly be an "H" but it looks like an "M."  I'm sure if anyone had a handful of vintage fender tags we'd all come up with dift codes for a few of the "tough to read" ones.  Going in order it would either be for the place of an H or the M line of options to begin.  It isn't like the tag reads "A41, M51, C16."  It falls right into place where it could realistically have been placed.  There is one right by the LH screw which is pretty much impossible to read and then the one in question. 

The car definitely came with factory air, lol...

The reference to the old etchings and "Ms" refers to the etchings I made when I first got the car.

You know the drill, you etch the fender tag and rad support, pen the vin and then start doing your best to write out the letters and numbers above your pencil etching.  I also took the tag off to help with the more difficult to discern codes.  What I came up with back in the day was the same as what I scribbled out a few nights ago.

I tried to make it clear that I really didn't think it was M51, but H51 AND was posting up to get the low-down on why M51 was "NOT ON TAG" as the decoder described.

My eyes are good but I'm not perfect.  I still say it looks like an M, but realize like I've stated it is most likely an H of some distortion.  I guess I should have just asked the question and avoided the reason why I was asking 

Hopefully that clears it up for you...The question was essentailly why M51 is not "on the tag."   NOT Just 6T9 CHGR pretty much gave me the info I was looking for   
Thanks for the concern and trying to help though

The same thing happened to me on my R/T SE's old fender tag.  It was H51 but looked VERY MUCH like M.  Chris straightened-me out back then too.  And Correct M51 was never on fender tags (found that out when my buddy had a sunroof car)...
