I must say that dist looks like hell. where has it been, under water?

looks like something got wedged in there and bent it. if you cant get it straight then you need to replace either that part or the dist.

I don't know the 77 so I don't know if the 2 wires are factory. either way, the signal coming out is still the same. you one + wire and one - wire. note: these are not really + and - like the battery, its kind of like AC power in your house.

I also don't know why your car has 2 extra pins on the CD unit or other than the connector is 8 why you could not goto a 6 pin unless you are trying to go back to original for value.

if you don't HAVE to be original the MSD is a good setup. if it ran bad I think you found a major reason why with the bent pole in the dist. the new MSD has a built in rev limiter that is adjustable with a dial on the outside.

you may also be able to find a 6 pin wiring harness and use a 6 pin CD.

check with jonnyH above. I think he may have a pretty good CD. by the time you source an 8 pin and have it repaired you may be better off with his.
just some options to think about.


back to the 2 wires.
all the ones I have seen are a coaxial wire. IE, one wire inside another. this is probably done to suppress noise getting on the wire. looking at your pic it does kind of look factory. most aftermarket terminals don't have that little tab sticking out off the back. that tab keeps the terminal from pulling out like yours did. the black holder also looks like it has holes for those 2 terminals.
without getting into this too deep, when connecting an MSD up the 2 wires are swapped going to the MSD. IE, the + is now the - and the - is now the +. so don't go by how it was connected to the MSD.
