Thanks, I had looked at the LMC catalog but it says as required which didn't help me much. As I said my truck had a plywood bed when I got it with three cross sills, two in front of the axle and one in the back about 16" from the rear. It had the reinforcing strip in front of the axle on the bolt row after the second sill. Looks to me like the reinforcement bar should go behind the axle on the bolt row in front of the rear sill cross member. That would provide more equal spacing. But I am not sure how the factory did it. The shorter reinforcement bar is what I am not sure of.
