I looked in the manual, can't seem to find anything on the rear power antenna. Any pointers as to how to replace?
Thanks,
Craig

It's probably not in the manual because it wasn't in the original design. Earlier cars had an antenna built into the windshield.
What's wrong with your power antenna? Are you sure it needs replacing? When I first bought my car the rear antenna didn't work at all, and after some diagnosing I found that it was because the line running to the radio was sitting disconnected buried in the center console.

Take the old one out, put the new one in.
You get to it by removing the carbon can access panel at the left rear in the engine compartment.
You will need to modify the mounting a bit as the replacement antennas are a different shape than the originals.
You will need to modify the wiring and eliminate the small relay in the driver side electrical compartment as new antennas use a built-in relay. Run the trigger wire from the radio to the new antenna. Get power and ground from the same place as the old one.

When I turn on the radio, I hear a noise in the rear, but it does not go up... So you don't have to pull the outside vent? Where is the relay?

I found I had to remove the driver's taillight to get to one of the mounting bracket bolts. I removed bracket and all because I was installing an aftermarket, not a stock replacement. It required a little modification to get everything set right.

It can take quite a bit of fiddling to get the antennae installed. It is not easy to get it to pass through the fins in the vent and come out straight and level. As Dave S points out, if you install an newer antennae they have the relay incorporated into them and you must remove or bypass the existing relay if it is even there and hooked up. Be sure to fuse your wiring properly and route the wires so they do not get pinched and then ground or short out. It is worth trying to get the original to function before removing. You can temporarily run some wires to it directly and see if you can get it to move. When installing an antennae you should be sure to ground it properly for two reasons. One, so it will go up and down, but two, so you do not get a lot of interference and a weak signal because the signal ground is missing. Not that you will get a great signal with the original Craig or ASI anyway, as radios go they are pretty junky, even for the 80's. Today they are garbage compared to what you can get.

The noise you hear in the rear when you turn on the radio is the antenna motor trying to raise the (busted) mast. So your relay and wiring are fine - to the old antenna.
Unless you spin the rivnuts that mount the antenna base bracket to the back of the left pontoon you can remove the antenna, together with its base, without pulling the taillight. Photo shows the access situation after the charcoal canister comes out (bottom plate of canister still perched on vent hose, dealer-installed "factory" antenna in place on this early-build car).
