Thanks, mine is on the drivers side, but I've seen it on both sides. Your Rs explaination makes sense. My Franklin Mint 69 Z-28 (great example of what the car should look like) has the bottle on the drivers side also.
My brother bought his 69 Z In 71-72, and it had a space saver with the can of air with it.I found one,not sure if it would pass for original,but its a B.F.Goodrich. I would have to check for what size-but like I said probably not original anyway.I just wanted one because he had one.
The (N65) Space-Saver Spare wasn't available with Z/28 or JL8 - only with 14" wheels. The (U69) AM-FM radio came with one center speaker in the dash, the same as the (U63) AM radio. U80 got you one additional rear speaker. With Stereo (U79), there were four speakers - one in each kickpad, and two in the rear parcel shelf.
Thanks for all your help - I'm glad I belong to this net. When I owned my ZR-1 and participated in the ZR-1 net, all I received was was in-fighting and politics. It's nice to see professional and knowledgeable responses to my questions!
