Bolt size

What is the size of the bolts for the lower control arms? I'm jut gonna be cutting them off and replacing them since the others don't seem to want to come off, so before doing so I'd like to just have the other bolts ready. Ill be replacing all the bolts on both front and rear lower control arms

Or upgrade to Grade 8 SAE:

Upgraded UCA axle bolts to: 2.5" x 7/16"
Upgraded UCA frame bolts to: 2" x 7/16"
Upgraded LCA axle & frame bolts to: 4 1/2" x 9/16"

FYI, the stock front LCA Bolt at axle and at frame is different, the axle end is longer.

I think ill upgrade to grade 8 considering I can't find any of the others in any hardware stores and nobody seems to help you there either. Thanks for the reply
