1/2 Lug Studs
I'm installing 12'' wide tires and need to upgrade to 1/2'' lug studs in the front and rear. I have already rebuilt my trailing arms with new spindles (they have stock lug studs installed) - I wasn't planning on going with this wide of tire when I rebuilt them. I've seen Norval's hub drilling tool used on the front hub, so I'm okay there. My question is regarding the rear spindle and 3'' lug studs...where would I have to drill a hole in the dust shield to get them to fit into the holes?

You would have to pull the assembly apart. You can buy hardened rear spindles with 1/2 inch studs. Unless you have a milling machine I would not attempt it at home.
Same thing up front you buy the 1/2 inch stud wheel bearing assembly.
The dust covers are actually just bolted to the caliper mounts. Just pull off the caliper and rotor and you will see what I'm talking about. If your rotors have ever been replaced the rivit heads would be ground of drilled out.

I went with Tom's rear 1/2 inch super steel spindles. Because my stock ones were rotated nearly one full shaft spline tooth from continues pounding. I also use the two inch adapters with my 6.5 inch BS 11 inch wheels

That's what mine looked like when I pulled them off...the splines were twisted. I decided to replace them with replacements from paragon corvette - next time I'll go with Tom's spindles, he seems to sell only quality parts.
