The fender would be correct number regardless of door or title paperwork.

Door tag could easily be reproduced to say anything you want.
And titles get screwed up all of the time even for newer cars.

Anything beyond that I would say is fraud to insurance company and potential future buyer.

[/b]That door I believe is original, have owned it 30 yrs or more, talked to the guy that was 2nd owner who drove it to school.  Was sitting in a field with workout 302 with the top loader in trunk. Brought it when mustangs were not that high and I don’t think previous owner would went to the trouble to Chang vin tag on door as I bought it as not more as junk.  just wondering if any other explanation ?  Not trying to sell as I had new quarters new fenders and floor pans, 351W , T5, electric steering, unisteer rack, so one of my grand kids will receive.  Taken a long time to get where it is, only thing left is Shelby drop and Daze adjustable struts.  Wish I could post a picture, don’t see any place to post.  If the door vin is fake then how was a titlle produced with A code.  Is it possible for a T code car and a A code car to have the same serial numbers if the door was changed.

Does the VIN on the inner fender say 6Txxxxxxxx?
Or does it say 6xxxTxxxxx?
Or does it say 6xxxAxxxxx?

T in the second position is the code for the Metuchen, NJ assembly plant. T in the fifth position is the code for a 200 6 cylinder engine. A in the fifth position is the code for a 289 4V engine.

Well...I'd say if it always had five lugs, 8" axle, V8 frontend, and the title says "A"...it's an A code.  The fender stamps likely were the result of "failure to communicate" back in the day considering the known history of the car.  My opinion. 

For title purposes, the fender VIN overrules the door tag.  I would get with your DMV to get it straightened out.  You don’t want heirs getting trapped someday if it ever gets ugly.
