front shackles

[coopertwpk]

This is kblazen my hard drive decided to go south so now im back .the update on front shackles, well so far ive discovered that my blazer has 7/16 upper bolts and 9/16 lower bolts and 9/16 drill bits are really expensive amazinzingly,so my question is how can ORD say their shackles have 1/2 bolts grade 8 when my lower one is 9/16 and grade 8 from GM?Ok now is the info I need if someone wants a set I need the length they want centerline hole to hole bolt size(earlier models seem to be 4" and 1/4 thick) mines an 88 its(center is 4 1/2 and almost 3/8 thick) the ones ive made are 5 on center and 1/2 thick.

Sounds like somebody drilled out your bottom bolt. Never seen one 9/16" from the factory and I have been under allot of K-5's
