Lower Control Arm Bolts
 

I have a 1991 D350 DRW w/4000 lb axle. I recently replaced all the front suspension bushings and tie rod ends and etc. but I had stuck bolts in the lower control arm bushings. I ended up desetroying the stock bolts removing them and then had to replace them with what I could find (Home Depot special) but the bolt is totally threaded instead of being a shoulder bolt. I would like to replace these with the proper bolts, but I cannot find them and I really would like to avoid pulling the whole thing apart to determine the correct size. I was just going to order the correct size from McMaster or Fastenal or the like, but I need to know what size it is. So, can anyone who has a bolt out of the truck and can tell me the following:

Shoulder diameter, Shoulder length, total length.

Thanks,
Tyler

I don't have the measurement, but I'm pretty sure they're 3/4". I had to drill the crossmember holes on my Ramcharger for that suspension.

Double check the bushing ID, and measure the span of the holes in the crossmember, then head to your local Fastenal. I use flat washers and nylocks for most of my chassis stuff, and they always seem to have stock. :tu:

EDIT: Raybestos 5651032 lower control arm bushing has a 0.76" ID
