Anyone know how to tell if a cowl tag has been replaced? I believe the rear side of the rivet is different when replaced???

Need to try and verify that a z28 is in fact a z28.

Any hints for other things would help too. I know to look for disk brakes, proportioning valve under the door, and I believe the speedo should be on the passenger side of the steering coloumn.

 

Actually the cowl tag wont really give you alot of info on weather its a z or not. the broadcast sheet/build sheet is more specific. I am at work now and dont have the publications that I would to referance this, but I am pretty sure.... of the top of my head that the cowl tag wont be that specific.

Check some of the links posted in the sticky for info till I can get to the pubs.

 

Actually, the trim tag will help, if it's a 67 or 69 Z28, but you didn't say what year yours is. A 69 would have an X33 or X77 code towards the lower right of the tag. The 67 Z28 tag will have a "4L" code towards the lower left, designating a 302 (Z28) engine. The 68 tag has no Z28 codes.
Even if a tag checks out, that's no guarantee that the car hasn't been forged with a phony one. Correct appearing rivets can be bought, but the installation process is something that not everyone can duplicate and make look "factory".
There should be a partial VIN stamped on the pad of the 302 block, forward of the pass. side head. Those numbers should match the serial # portion on the VIN tag. Stamped on that same pad on the block there should be either a "DZ" suffix code (late 68 & all 69), or an "MP" (1967), or an "MI" (1968), or an "MO" (67 & early 68).

Looked at the car I posted about yesterday. Never got to the cowl tag to check it as most other issues failed the sniff test. Car had 12 bolt rear but 5 leaf springs, shift tunnel was cut with a torch for the 4 speed and hand no nuts welded under the mount holes, no tach, black grill, no brake prop. valve under the drivers floor...........

Guy was p-o'd when I stated it was no z car. Oh well, I guess I wouldn't be happy if the project I paid top dollar for was suddenly worth 1/4 what I paid.

Here is the expired auction id link:

only 1969 Z/28s that were built in Norwood Ohio and late in the production run had X33 or X77 codes

 

Even the good clones have correct "looking" rivets for cowl tag. Unfortunately, may claimed Z28 are not
