i have a 72 blazer. ive had it for about 3 years and havent really done nothing to it. i bought it really cheap and i want to start fixing it up and also learn how to fix it as well as what parts i have on it like transfer case, tranny, etc. anyways, one of my first questions is: my fronts are 6 lug and dont know what type of axle, my rears are 8 lug and dont know what type of axle. what do i need to do to make the fronts 8 lug. parts and etc. the reason is cuz i want to put some 38 meats on the beast. thanks for all the help and info in advance that is generated.
