Oh yeah that's part of the fun of bringing these sexy ladies back to life i love to rescue sleeping beauties this will be the first z im bringing back to life however i have some experience with vehicles at rest for ten years plus 

Thank you for the information and concern!

I just got my girl home i looked and there is no door tag ?  

The tail lights say 69 is there another way to find out?

I think the hazard switch on a 73 will be a pull knob that lights up green and a 72 would have just a toggle switch. as well the faceplate for the heater controls will be back light on a 73.

It does have a toggle not a knob

My '72 has a toggle too.

 

I wanted to thank all of you for replying 

I came to the conclusion that it is in fact a 1972 because the heat shield pattern and the linkage set up matches a 72 plus the toggle switch for the hazards And also the front bumper 

Thank all you z lovers for helping me understand my new found love better 

P.s I will have her ready to be fired up tuesday for the first time in over 30 years fingers crossed 

Changed the fluids spark plugs lubed the cylinders hand turned a few times going to lube some more in the morning cleaning the fuel tank and lines tomorrow and i am waiting for the carb tune up kit should be here tuesday morning by the afternoon she should be ready YAY!!!!!

I really like a Fram G-2 on the 240s fuel tank outlet hose. They're cheap and clear so you can see if you have sediment in the tank without dropping it. They're like $3 @ walmart.  

Thanks ill get one tomorrow

Also, 73's have a delay wiper setting. The earlier cars don't...

look on the firewall above the brake booster. the serial # will be stamped there. the serial # will tell you the build date

Thank you sweatybetty i will look in a few mins
