Hi Tom. I'm not sure how mechanically inclined you are (or want to be!) Removing the OEM pulley and installing the press-fit smaller pulley requires some specialized tools. All the other steps are relatively straightforward. The first step (and perhaps the most intimidating) is removing the SC from the car. In actuality, this is very easy. You just need to be careful with the rubber vacuum hoses on the rear passenger side of the SC. To give you an idea, once the car has cooled down a bit, Ryan and I can typically have the SC off the car and on the bench in ~20 minutes.
Once on the bench, you would typically use the aforementioned "specialized" puller to get the OEM pulley off. Then you remove the SC snout so that you can press the new pulley on (and you are pressing directly on the back-side of the shaft). Anyway, where I was going with all of this is that if you sent us the SC snout, we could remove the OEM pulley and press on the smaller pulley and return the snout to you. Not sure if that helps at all - but at least an alternative.
