If you have a 1997 explorer your speedo is driven by a speed sensor and gear in the transfer case. The later models got their speed signal from the rear differential. I don't believe a 2000 f150 will work as it used a rear differential speed sensor as well. For mine I was able to find a 1997 f150 to get the transfer case and it was the correct style. As far as the shift boot, I tried the f150 and it just didn't match the contour of the transmission tunnel. I ended up using a boot out of a car a friend was taking to the scrap yard at the time, I believe it was a 90's fiesta or festival??? But I honestly couldn't say for sure now it's been over 4 years and my memory sucks. On the upside I did the lift, bw4406 swap and been on 35's for 4 years and still running great and haven't had a single
Problem with any of it.
Edit: Ok forget everything I said... Lol. All the other posts didn't show up in my phone when I clicked the link. I didn't have to deal with all that, I got lucky and scored the correct year t case very easily for a great price. Hope you get that all figured out!
