I went through the same dilemma for over a year, had 3 starters, new battery, new alternator, still would not start especially when it was hot. The starter would click but not turn over. The problem was the small wire going to the starter. As these cars age, there is a build up of resistance from all the lengths that small wire goes from clutch switches, relays, etc..etc..... The solution is to go get yourself a 12V relay and wire it up in the engine compartment. The relay acts as a power booster for that small wire going to the starter, your car will start like never before. My car starts so strong now that it is funny. The wiring diagram available at the12volt.com, goes like this Connect terminal #87 to 12 volt constant, #85 to ground, terminal #86 to the ignition side of the small wire, and terminal #30 to starter. - 88gts
What you want to do is get some 12 or 16 gauge primary wire and a fuse holder with a 30 amp fuse. Following this diagram, first find a location by the battery to mount relay 1 screw. Get some solderless spade connectors. Connect fuse holder to battery (w/o fuse for now) extend the wire to the pin 87, ground pin 85 to the chassis with short wire, find the small wire going to the starter unclip the disconnect by the header, cut off this disconnect, solder on some longer wire to reach the relay connect the side going to your ignition switch to pin 86, then connect the starter side to pin 30, finally put in your 30 amp fuse, and start her up. Hope this works for you. Let me know.

I think I used 12 gauge primary wire for all of it just to be safe, and some of those yellow solderless spade connectors (same kind used on speakers) to connect the wires to the relay, but I soldered the wires around the starter due to the heat. I think it took me about an hour. It is best to plan it all out get all the parts first. This is actually the only way to wire the relay it is only 4 wires. Good luck! - 88gts
The relay you need is available at a car stereo shop or auto store shouldn't be over $5 US dollars. The relay should be SPDT. Single Pole Double Throw Relay.
