Thanks, everyone. The main problem here is a concurrent lack of funds, knowledge and talent.
I can certainly unbolt old parts and bolt new parts on, what to do from there is beyond me. I have no idea how an A/C system works. I have been in Houston long enough to know that when it's approaching 100 degrees and the A/C doesn't work.....well, that's no good!
Mitch, if you're willing to take a cursory look at the situation I'd certainly be appreciative. I'd love to take a look at the Cobra's anyway! I'll give you a call to set up a time that's convenient for you. I'll send you a PM.
Thanks again to everyone for all the advice.
Doug
