QUESTION 1973 z1 speedometer gauge instruments

I'm interested if any one has a very good high resolution picture of 1973 speedometer they could send me or if they would like to sell it to me; Also does anyone know of a good forum that would know all the different stamped id numbers on the 1973 z1; such as the rotor, swingarm, exhaust pipes and so on. Please if you know of other forums which are specific to the z1 models that would be great. Thank you. Also if you have a high resolution picture of a guage could you send it to my email. mjb4mjb4@yahoo.com. Thank you very much for any help.
