67 AC AREA leaks

Thought I had them all - but then this is 67. The recent down pours in the South have caught many by surprise and I am one. The street side of my Sovereign showed signs of leaking and not just a little. I cover the area with a tarp and begin looking for the leak. Water was coming down the wall from the roof area and the AC catch pan overflowed on to the floor. I had never thought that the pan was catching water from a leak but it was and discharging it out the tube. While doing work on the belly pan I had the unit in an odd position with drainage to the curbside rear and thus the water coming in at the AC could not flow out properly and this caused the overflow.
The wall leaking could be a seam leak and that is OK for I will reseal after I strip the clear coat. How do I get to the small area under the AC where the AC leaks and maybe the other leak is coming from.
If it was a newer AC I would have no or little problems but this old unit I have never seen anything like it before. I have done my research of old post but all I find is on newer units.
Any advise on how to handle the old AC unit leaking to the inside of the AS? If the subject has been posted on an old thread, how do I get to it? Thanks

If your AC is an old Armstrong unit it could be a couple of things. First, check all the mounting screws around the edge of the unit. The second area prone to leaks is where the freon and power wires go thru a hole in the top. It has to be caulked well. Finally, there is a small hole where the motor shaft for the fan on the inside goes through the top. That should be OK, but if the motor has been replaces that gasket under the plate holding the motor could be bad.
I have a lot of trouble with leaks on my old Armstrong. I'll get it fixed and then it starts again. Total frustration but it cools so well I hate to just dump it.

From 1969 and older, the factory AC was made by Armstrong. They never used a drain pan.

Rain however, could come through the AC, in 3 places.

1. The 2 AC copper lines.
2. The city power wires.
3. The blower motor gasket.

The first 2 are easily seen. The 3rd one requires the removal of the fan blower motor, so that the gasket can be replaced.

Armstrong AC's were used up to and including the 1979 models, and none of which required a drain pan.

The drain pans were first used with the 1980 models, that used the Coleman AC's.
