No. At least not without modification. Contact point distributors were still being used in 1973, while electronic ignition (HEI) was used in 1983. Fuel injection was also a possibility in 1983, or at the very least, an electronically metered carburetor, which means an ECM is also likely, which obviously didn't exist in 1973. Chances are the wiring for the alternator is also a heavier gauge in 1983. in other words, NO, NO, NO!!! The amount of headaches and modifications needed to make the older harness simply aren't worth the trouble. Find one from another 1983 Chevy!!!

You can possibly make it work, but it won't exactly fit. Length and wiring harness will both likely be different. Now, a '73-'77 steering column for ANY GM A body WILL work.

Do you need to remove the engine to install a new wiring harness on a 1966 VW Bug?

It would be easier in the long run but I wouldn't. I just replaced my wiring harness in my daughters 73 SB and although it was a real pain and took forever because I am 240 lbs, I did it without pulling anything. Well, my daughter pulled my finger once !!

Yes. The only difference besides the inside door panel is the 73-74 doesn't have the wing vent window like the 68 -72.


Do 1972 Chevy nova back bumper fit on a 1973 Chevy nova?

No, the brackets & everything are different since the body changed that year. The 73 has that wide strip between bumper & body so the curved sides longer to take up the gap. I think wheelbase also changed slightly. The 73/4 are the same.
