fit isnt the issue, the original bolts were longer on the crossmember to frame, and used a spacer on top of the bottom of the frame rail (with the bolt either going up or down into it, nut on the other side) because longer bolts are able to be tighter or something. Its only on the 4 crossmember to frame ones, the rest are fineI am using new hardware. The old stuff that came off the crossmember was nasty and missing a bunch of pieces. I got all new bolts, nuts, and washers for the crossmember. I didn't get any bolts with the transmission so I got some grade 8 bolts like Bucket said earlier and they seemed to fit.
