I am looking for mounting bolt sizes for a rear bumper. 2004 model. I combed the threads here and all seem to be asking about the underside bolts. I need mounting bolts...the 4 main ones (2 per side). I bought a Mopar Rock Crawler bumper and need to get bolts to mount it. Picture attached for reference.
Thanks!

Looks like you should be able to measure the holes and find a bolt that will fit. You need nuts too. I personally would use grade 8.

Yeah, the bolts need nuts on the other side so anything that fits through the bumper and frame cross member will do fine. I'm pretty sure I used 1/2 grade 8 initially. Had to go down a size when I installed my poison spyder frame tie ins because the hole in the poison spyder bracket was smaller than 1/2 inch.
