bolts/studs for s/b factory A/C

[clean cut creations]

Thanks Harold! These are all exaust manifold bolts, including the right one, and that SHOULD be for a dipstick retainer. The truck these came from is a 2WD but the previous owner installed drivetrain and several options like factory AC from another truck...POSSIBLY a 4x4? The truck was just missing some important AC brackets and we got that squared away with the help of another post. I just couldn't get info on proper bolts and I didn't want to trust the previous owners building skills! Thanks for the info!!!!
