1960 c10 Rear wheel studs too short
 

Apologies if this has been covered before I found posts on 5x5 but nothing on 6x5.5 lug pattern

I bought a set of aluminum aftermarket wheels and how I've run in to a problem. I only have about 1/4 inch of exposed threads to grab buy the lug. It looks like factory studs are 7/16-20 and have a knurl of .564. I've searched every end of the internet and I can't find a 1.75-2 stud with a .564 knurl closest I find is dorman 610-025 they are too short or Dorman 610-156 and the knurl is undersized at .557

What have the rest of you done in this situation?? Fronts i have conversion rotor's on a 78 crossmember studs on that seem to be ok.
-----in regards to this new crossmember it looks like its about 3/8 too skinny to fit on the out side of the 60 frame rails. Anyone else deal with this problem?

After market wheels.
No problem.
Just use the correct lug nuts. There are several types.
Which wheels?
You got a pic?

Not sure if this is working or bot but should be a photo of the wheel and thr lugnut

Center bore of rear wheels too small causing the wheel to sit on the axle flange(?) thing?

Try using some "ET" style lug nuts

Can someone define any of these specification terms?

I've had something similar, but it was the outter rim of the drum contacting my wheels. The center hub still went into its hole, but it wasn't totally bottomed out.

I am assuming that the knurl is the part with the splines. Is the knurl diameter measured from the valleys of the knurl or the peaks? What part is the nose? How do you measure the wheel stud hole size?
