it doesnt look hard, i just hate working up under the dash, also the ac compressor i ordered has a 5 spline pulley, but my current one has 4. im assuming a 4 spline belt will fit on the 5 spline pulley just fine. im guessing its not going to hurt anything to just have the extra notch on one side. but if it will matter let me know, i dont want to swap the pulleys/clutches out for nothing if its not going to hurt to leave it.
