Looks like they have just a bit more clearance than my Cragar SS-which i know needs a spacer on the early 4 piston disc cars. Seems very close. Not much help, but figured I would bump the thread for more input.

Here are the Cragars which I know require a spacer for the 4 piston calipers. Hope this helps someone.

I recently put 15x4 on my 67 with 4 piston calipers. I had to use a 1/2 inch spacer.
My problem was finding the correct length lug nuts. Finally bought long ones and
Had them cut to length.

Good point Richard! When using the spacer, it is best for 6" and narrower when using popular Cragar offsets, though custom ones can be made for 7" fitment. If you run longer wheel studs, then standard lenth mah wheel lugs are fine, but you'll need them to be open so the stud doesn't bottom out on the lug cap.

Scott, i suspect you'll need the spacer and then some longer lugs trimmed down. Hope to see pics of what you're working on!

If you go with longer lug nuts be careful about getting the length right. You don't want the lug nut
To bottom out on the hub. We have a machine shop at work and those guys help me figure out
The measurement and cut them on a turning lathe.
I didn't want to install longer studs so I could change out to other wheel sets I have.

Good luck,
Richard
