The OEM bolts are 3/8"-24x1-1/4". The 1-Ton requires 3/8"-24x1" on the driver's side only; there's space on the other side for the 1-1/4".

I use McMaster-Carr socket head bolts 91251A424 and 91251A426 with high-collar washers 90073A231 for my 1-Ton. I find them easier to use than the 91271A644 with 12-point heads (probably because I cracked a 12-point socket on them).

Ken,

If you have to do much with those, find and buy the hex drive from a Snap-On Guy. There may be others, but I found out years ago on hex. European Triple square and heavy Torx that this can matter a lot.

I bet the reason you broke that 12pt was that it was a 3/8 drive. That is why I ordered a 1/2 drive for this job.

Matt
