These new U-bolts are what you need to install a GM Dana 60 front. There are two u-bolts for the drivers side and one larger one for the passenger. All the U-bolts are 5/8" dia x 10" long and include nuts and washers. There are two bolts and washers on the passenger side that hold the spring plate. Those ARE included with this kit.
If ordering a group of multiple u-bolt kits (for example A D60 and GM 14 bolt U- bolt kit) we can combine shipping. Please email or add a note to your order and we will adjust the shipping amount to the lowest possible rate.
