HI, I checked out that Mopar Performance article that was sent as a link the other day. It had to do with swapping out the old RV-2 compressor with a new Sendan (sp?) unit. If it were me. I would do it in a minute. I used to have a '79 Dodge Magnum with the RV-2 compressor. Boy did that thing bog the engine down when switched on. I just figured that that was the way air conditioning had to be until my friend stopped over with his '78 Ford Granada. Just for the heck of it I checked out his A/C. His was equipped with a newer style compressor. What a difference! If you switched mine on, the engine would start shaking and rolling, and it was really noticeable that the A/C was engaged. His? Well, I couldn't believe it. Switch it on - nothing. Except LOTS of COLD air! Amazing. Hardly any noise, smooth, I was really jealous. If you are not worried about being original, I say go for the switch. It'll make your Imperial an even smoother ride.
