Also, I would look over every inch of the A/C system to find any signs of a leak, especially if you fill with R12.
There is a GM certified tech close by who has his own shop . He worked at a GM dealership for 10 years and has all the other certifications , so I'm going to dump it in his lap probably tomorrow . To tell you the truth I could do some of it , but I really don't feel like it . At 67 years old , I have better things to do with the time I have left If ya know what I mean ?

That'* great you now have the PA!!
You are lucky you have someone to work on the car so close by. If all it needs is AC & rad flush, wow, that is really good news!
Make sure all the brakes are inspected, & a brake fluid test strip would assist in knowing if it needs a bleed or not. I would normally also want to do new transmission fluid into Dexron VI and a new filter too.
Power steering fluid bleed or suction out the old stuff and get some new in there.
Can't wait to see more photos of the Pk ave soon..start clicking some!

I am going to drop it off at the guy'* shop this afternoon and let him go through it from stem to stern . That said so far all I've found is the AC is not blowing cold air , the fluid in the radiator bottle looks pretty old and last night I found some moisture in the trunk . I pulled all the fabric and the spare out and it looks like new except for a little surface rust where the jack sits . It looks like it just started leaking very recently , any one have any ideas on where the leak might be ?

Member William E had a trunk leak, if I remember correctly it was coming in from around the license plate.
Often it is best to do a water test. Take a garden hose and allow water to flow down/ around trunk seals/license plate area.
See if you can notice an entrance point afterwards.

There are seals around the tail light bulbs, as there is a cutout. I also have a leak, and i suspect mine is coming through at this spot.

Before I took it to the shop today I got in the trunk with several lights , my neighbor shut the trunk and started hosing the trunk with water . Before we started there was a bit of water pooled on top of one of the tail lights , I wiped it dry then while he was hosing the car the water begin to pool in the same place on top of the tail light . Where exactly it is coming it I couldn't see but it is definitely entering in that area . When I get it back from the shop I'll remove that rear light panel to try and figure it out . If and when I figure it out I'll post the result .

I had a similar trunk leak, and at first I thought it was from the seals around the tail lights, but I replaced those, which cost me about 28.00 each, then I removed my main trunk seal, sprayed the inside part of it carefully to remove some dirt that had gotten in there where the seal contacts the trunk lip, I then put a nice bead of silicone inside of the gasket, I wanted to use something better, but silicone was all I had at the time, I put the gasket back, and after that I got no more water getting in my tail light bulbs, and in the trunk.

Thanks William.
A longer lasting product for sealing these areas are urethane based.
Marine grade is the best Sika-Flex, next would be a tube of roofing urethane/caulking.

That is the stuff Art, I always forget the name of it, I am pretty sure the stuff they put in the gaskets like these is urethane based as well, kind of a black sticky tar looking stuff, that was what was in my tail light gaskets anyway.
