To update my small part of this thread I used my Apex on Imogene Pass to winch my buddy's CrewMax Tundra up some steps that were too slick for him to get up. Not a huge test but it worked as it should.
I have been having fun with that all day. I tried fitting it on top but the grill and the power wire were interfering so I decided to see if I could mount it on the winch. It took a bit of clearancing on the core support but it fits great. I may take a bit more off if it rubs.
This thread is awesome. Thanks to @Brandon Ryder for figuring out everything for us. I put the 03-06 ARB on my 98 LX with the Apex winch this weekend. A couple notes. Because of the way the LX grill opens with the hood the winch clutch is right there. I bought the knockout plug but didn't...
