So, I can't help you on which motor to run. My question is, which interior are you running. Either way, you can run A/C. There are write ups on this site that show different ways of doing each. The parts aren't easily going to match. For the most part, you either have to use the SN95 box or have a hose built to match the SN to the Fox, or have a fitting welded onto the Fox box to match the SN hose. If you hit a dead link, reach out to the member who posted it to see if they still come around and can fix the link or if they posted it on another site. Lots of builders come through this site, build their ride and then don't hang around. If you post a build thread, you can put your pics right on this site and then there is no link to break. If you decide to go with the yote motor, the same connections will still be an issue. Having the fitting replaced can also let you put a elbow in that helps give you head clearance, but makes you need a slightly longer hose. The last one I did, I took my hose and core down to an A/C shop that could make hoses and showed them what I needed. They changed the fitting on the core and built me a new hose that was perfect. That was 10 years ago, but I'm sure there are shops around that can do it.
