What's up bud I myself have a 82 720 and I've opened the torsion bars all the way and also purchased rancho shocks who's maybe gave me 1.5 inches the best lift will be a body. As for winches go I just purchased a smittybilt xrc 9.5 and I love it. As for your gears when you pop the hood son the passenger side on the fender close to the firewall there will be a silver tag on it will have your truck info as in Vin color what engine you have and towards the bottom you'll see HF then a number that is your gears. For me mine says HF43 so I then have 4.375 gears
