will the distributor from a 85 rx7 {12a ?} work in a 78 cosmo {13b} ???
I too would like to swap my points for electronic goodness, all my local wrecking yards have is the rx7s with the water oil coolers, = 83-85, which = 12a , yes ?

Yes it will work, the one I'm using on my '74 model 13b is actually from an '83 12a. Just make sure to get the coils too.

are there any tricky timing things that I need to be aware of ?
as in I figure that my getting a distributor from an 83-85 in the junkyard for my 78 13b should be pretty much exactly what you are running as far as port timing and distributor vaccume and centrifugal advances.
Just make sure to get the coils too.
sorry to ask so many questions but I wanna pick your brain for what you learned as much as you will tolerate
THANKS !!

Try to set the junkyard motor to the timing mark on the main pulley before yanking hte dizzy. Mark the dizzy so that you can get it in the same position when you try to put it back in your car. Set your car to the 0 timing mark before putting the new dizzy in. That should get you within a tooth of correct timing.

I would also be a good idea to get the wires with the plugs for the ignitors, just unplug them from the dizzy but leave them connected to the coils so nothing gets mixed up. The only wires u should have to disconnect to get all this out of the car is the wire for the tach, not sure the color, and the black wire w/white stripe fromt the + side of the coils.
O, and I don't use the vac advance. No vac lines going to dizzy.

a bit of reading leads me to wanting another ignitor and coil so I can get some of that goodness.
I went to my favorite junkyard to snag the distributor & coils from their '85 and it was GONE ! the whole car had vanished in less than a week. odds are that it was crushed.
so I went to the only other local yard with an '85 on hand. it had been hit in the front, such that there was no way to crank it to 'tdc' before yanking the distributor.
ah well, I will just have to be as precise when installing it as I had planned to anyway
I wanted to snag the wires & plugs for the ignitors but the wires ran into a bundle that vanished off into the depths, since I will be making the wiring up anyway fabricating plug substitutes won't be difficult.
$50 for '85 distributor with ignitors, coils, and spark plug wires.
