How to change a distributor cap on a 1974 chevy nova?
There are 4 hold down screws that you push down on and twist to take the cap loose, get your new cap and replace the wires into the new cap exactly the way they are in the old cap, take the old cap off and put the new cap in place and twist the cap just a little until you feel it seat and then push down on the screws again and twist until they lock under the base of the distriburetor.
