Case 530ck or 580ck backhoe bucket pin size?

I am doing a bit of work on my backhoe bucket,and have my pins out.The pins in mine are worn,but i am going to machine a couple new ones to replace these with,but after measuring,these seem to be a very odd size of 1 15/32" i would have assumed they were 1 1/2" as thats what my pins seem to be on the loader.Maybe a previous owner had pins and bushings made an odd size for whatever reasons.One of our Case experts must know what size the pins should be???
