I was wondering what companies make a twin stick for FJ40's. I have an 82 with a split case and would like to be able to run low range 2wd when I don't need 4wd. The rear locker gets me pretty much everywhere mellow that I need to go and I would rather save the wear and tear on the front driveline and axles. Also, is there an easy and/or cheap way to do this yourself?
