What is the size and thread count supposed to be? The ones I removed from mine are 7/16-14 1" long. Crazy odd size I guess as no one in town has them including Fastenal. I see AMK offers a kit but it does not specify sizes.

Try a 1.25  with washers, an ag implement dealer would have them

 
Did you try NAPA? They usually have a good selection in their stores. They show 7/16-14 x1" in both grades 5 and 8 on their website, but say to check store for availability.

 
Thanks guys. Well I didn't think to check first but went back to the auto parts store and asked for the bolts for a 351w and sure enough. Yep we have those. ARP for $12.00.
