They are u bolts not straps ,my bad ,63 are 5/16 and the 71 is 3/8 " diameter bolts or close to that size . I would have to go measure for sure, so I went and looked and the pad that the u bolt slides through is 1 " on the 63 and on the 71 it is 1 1/2" I wonder if it takes a strap and bolts any one have a # book 63 is 3896838 and the # on the 71 is 3856525
Looks like I need the straps as the yoke is threaded ,see sometimes it pays to talk to yourself or think outloud .
