How to ID 1968 SS or Z28 camaro??

[Big Squeeze]

Thanks guys.........It does have the tire decal still on the glove box door.......I forgot to mention that it's also got power disc brakes......the car appears to be all original and untouched except for the paint and engine rebuild.....

It does have the speedo cable coming out of the right side of the column and goes into the trans on the passenger side....

Where is the engine pad??

I glanced at the transmission but didn't see a number......Is it stamped into the case somewhere?? It was pretty greasy so I probably missed it.....

Here's a pic of the tire pressure decal from my phone.....
