i welded up one of the spider gears in my stock rear as i did not want a full locked posi .. the results shocked me .. it will spin the welded wheel at will .. it`s like i'm driving on ice .. the little chevy V6 dont have 700 horses but it acts like it does .. i have bought a ranger rear and will put in in soon .. it is only 1 inch wider than stock .. i know i can drill my front rotors for 5 lug to match but i dont know if i can drill the new rear to 4 lugs to keep my existing wheels .. and it has that bolt on rear coupling that i will have to deal with ,, we will soon find out .. i have welder and torch .. it will go in ...
