Cowl tag X55 or X66

[ssl78]

check the X code on the trunk divider behind the back seat and see what it says. It sounds original enough for it to still be there

What's the inside measurement of the heaterbox opening where the heater core would be mounted? There's a difference between a BB, and a small block. Lotta folks will change the outside. Very few will change the inside. If the heater core is original Harrison, it should have a date code on it to correlate with the build date of the car.

You're right! There was an X11 Z28. Just one, so it can happen......

So if their is one than their are two, the car with the other trim tag that should be on the Z. I guess the 6cy X77 I have is REAL!!!!

There was a guy with a L6 VIN that swore it was a Z. Drivetrain dates were all over the map (since nothing was original)!

Sounds like we have a match.

Thanks for the comments, input. I have taken pics of the cowl tag and the vin tag but the images are too large and so not allowed to attach to my post. I have the heater box and heater core clips in on of many boxes and as yet have not found them.

Here's the pics.
Original tags for sure.

Does it have the original axle? Do you have the axle code?
