The new Motorcraft 850 cca battery in my 88 T C has dropped from 12.7 volts to 12.35 volts after not being driven for just 2 days. Is this normal ? The car only has 48k miles & the alt. was checked at my Ford dealer as being good.
I am also wondering about dues....how to pay etc.  Thanks !!!!!!

Assuming the car started normally, I wouldnt worry about it too much.

Might want to check current draw from the battery with key off, doors shut so dome light off, etc. Depending on aftermarket accessories like alarm system, stereo amps, etc, draw should be under 50 mA or so. If significantly over 50 mA, (like .1 or .2 amps) look for glove box light, trunk light, etc staying on all the time, something that draws current plugged into the cig lighter plug that stays powered up, etc
