The '75 has two pretty large cracks. The '78 has a full cover so I can only assume that it is in pretty bad shape or the previous owner wouldn't have put the cover on. I think the '75 has an ammeter while the '78 has a voltmeter. That's one reason I was planning to just replace dash and all. I don't know how much trouble it would be to change the '78 harness to work with the ammeter. I suppose I could just change out the meter, assuming that the wiring is the same. I still need to do some research on that. Good advice on the injectors. I start the '78 once a week and it's running pretty rough. I've seen several suggestions to use witchhunter.com for injector cleaning. Their site says $21 to clean and test. I guess that's the way to go.

I have a 1975 280Z that I am in the process of restoring. I bought it from a guy who was planning to replace the l28 with a v8. The body is not too bad but the motor and transmission were out and according to him it was not running when he bought it. I've stripped this car and am in the process of repairing some relatively minor rust areas and getting ready for paint. I also have a 1978 Z with a salvage title. The body is rusted very badly but the motor runs and has good compression. It is in pretty good mechanical condition and I know that it will run. There's a problem with the fuel system retaining pressure but I don't think that is a big problem. My question is how much of the original '75 should I keep. I'm tempted to take everything that will transfer from the '78 to the '75. I know that gas tank is not compatible. Although I've considered changing the spare tire tub so I could use the '78 tank, but I think both gas tanks are in about the same shape and will need to be de-rusted and sealed. And I like the idea of a full size spare. Is there anything else that won't transfer? I guess it would only be bolt holes lining up and that sort of thing at this level of replacement. So my plan is to take the dash, wiring harnesses, ignition, ECU, engine, front and rear suspension, transmission, etc from the '78. Other than the dash I will keep the '75 interior as stock as possible. Alternatively I could go with the '75 parts and keep everything original. It will be more work and will likely be more expensive. I know that the wiring harnesses need work and that is probably why it wasn't running. I found several burned/broken wires as I was stripping the car. I'm looking for opinions and a sanity check. Am I missing something? Is it a mistake to do what I'm planning? What would you do? I should add that the purpose of this car is for me to drive and have fun, not to show. I've been reading and learning on this forum for months. It's a great resource. Thanks everyone.
