I have a '48 DRW 3800 that I picked up some modern 19.5" wheels for. I am going to try to reuse my old clamping plate but I noticed the lug studs are smaller than the lug holes in my new wheels. Do I need to get my hub drilled out to put in bigger studs or can I run it as-is?

If so, the wheel registers on the hub, not the studs. Is the I D of the clamping plate the correct size to fit the hubs?

I was not sure if I'd have to be concerned with there being some rotational play, sounds like not?

I'm running 19.5" wheels with 5/8" stud holes on my DRW 1 ton with original 1/2" clamp plates and studs. The wheels are hub centered.
Just rotated the wheels tight on the studs as if driving for the rear and the other way for the front as if braking. Then torque nuts to spec.

Does it have five studs in the front and ten in the rear? | | | | | Joined: May 2015 Posts: 35 Wrench Fetcher | | Wrench Fetcher Joined: May 2015 Posts: 35 | Thanks for the feedback, that helps a ton and I should be able to get the front end back on the ground today!
My DRW 1-ton has 8-lugs on all four corners. The front is set up for a 'dually offset' (for lack of a better term) wheel. | | | | | Joined: May 2015 Posts: 35 Wrench Fetcher | | Wrench Fetcher Joined: May 2015 Posts: 35 | Ok, new question now. What I am finding looks like I need 90-degree cone lug nuts, where can I find these? I can find 9/16" and 5/8" all day but not 1/2".
What I took off just look like standard hex nuts but I doubt those are stock. Am I able to just use a standard flanged nut?

Or is there a nut plate that all 8 bolts secure(requires tapered nut). .
