I don't think the A/C compressors are compatible--one used R12 the newer uses R134--completely different refrigerant. However, it is supposed to be possible to convert over to the 134. You should check with an A/C shop and ask for several opinions on this.
On the clutch/transmission problem, it could be the clutch not fully releasing (bad hydraulic slave cylinder) and/or bad synchros within the transmission. Either way, if the problem is not fixed, the transmission could be damaged or, if the syncrhros are already worn out, it already needs repair.
Sooooooo yah, i got my car back from the shop and i had them look at the rear tire for the screeching noise but they said "OH, IT'S FINE..YOURE TIRE IS JUST RUBBING ON THE BODY WHEN U TURN THATS ALL" HAHAHAHA deff. NOT!!! they said that they couldnt find anything else besides that which is from my ties hitting the body when i have ppl in teh back seat due to huge tires. but that doesnt screech, it makes a rubbing sound thats all..this is a loud, ear piercing noise and its getting louder and louder..gets really annoying especially when there is some hott chicks on the side of the road and i come down the street and i know theyre thinking " DAAAANNNGGG THAT CAR IS SWEET" until i take a left turn and theyre like " UGHHH WHAT A POS!" grrrrrr...
