Does anyone know the bolt size and length of the bolts that attach the lower control arms to the frame. need new ones and do not have old ones off as yet, badly rusted. Would like to use new.

new ones at proper grade strength aren't too expensive, 3 on each side, 21mm I think. I can check at work tomorrow on length. I can maybe get P/N with size listed.

Arm to bracket or bracket to frame? Vertical bolts or Horizontal?

yes they are. These are high torque to these bolts. The front is almost 200 lbs and the rears are like 171 but make sure you check its been over a year since I did mine. Dealer charged me 4 dollars each.
