Steve-I read your post last night and looked up the info to reply today-I'm glad you got such good help and you're happy with your local dealer. Remember them when the yellow machine salesman comes sniffing around=).I contacted Bobcat and they replied to my email. That customer service on a 29 year bobcat. These bolts are a Bobcat part number 17C820, which is a hex head,grade 8 bolt , 1/2" diameter and 1 1/4" long. You will want to contact Hamilton Equipment for pricing information. This is why people buy Bobcat.
