What is the size of these bolts? Mine were completely rusted to pieces but the bushings were in good shape, so I'd rather just pick up two bolts from the hardware store instead of the whole kit.

 

7/16" x 2-7/8" bolts. Wrench/socket size on the bolt head would be a 9/16.

 

Awesome! Thanks for the quick reply.

 

actually on an original core support mount bolt ,the head of the bolt was 3\4 " and it used a 11\16" staked nut
I just took these original core support bolts off of a Lansing built 442 , 3\4 " head on a 7\16 " bolt with a 11\16 "staked nut ,maybe other plants used bolts with a smaller head .

 

I measured an original bolt BUT I was wrong on the bolt head size. I just looked again and the original bolt head size is 5/8" instead of 9/16".

I also checked a repro set from Inline Tube and the bolt is still a 7/16" bolt but has a 11/16" head size and their bolt length is longer @ 3-3/8".
