66 Cuda- fitting wheels over 11" drums

[MechNerd]

I know I'll probably have to refine my question, but has anyone been able to fit 15x7 4" BS VN215 Torque Thrust ll's over an 11" drum? I got some info from Summit that said the inside surface that bolts to the drum is 12-1/4" dia., but that's all they could tell me. The 11" drums start at 11-1/4" and taper out to about 13-1/2" dia. in 4-1/2" of depth. No one could come up with a reasonable answer, so here I am. Again.
Another possible option is 16x8 4.89 BS, but I don't know if I can get them under the car. Any help would be appreciated. If I sound confused, it's because I am. Thanks.

Why do you have 11 inch drums? All the way around?

No, just on the rears. Do I want to change them to 10" or something else? Trying to avoid it.

Do you have disc on the front?

10" drums. SBP. Putting a B-body 8.75 in the rear, further cluster-fying the situation.

I cannot imagine they won't. My 69RR and the 64 426 were both 11"

I have to ask- you got 15" wheels to go over 11" drums? That would be the best news this week.

4.5" LBP, for the 8-3/4 I'm
putting under it.

Oh, OK, I misread the original post...factory steel 15" rims would all fit, & many 14" ones 'cause they're steel & not that wide, but that's not Your question. I'd go to the Mfr's. Site & look for spec list/diagram/blueprint sheet, or call them directly. Most rims are made to clear OEM brakes, which these are, but just the same......I'd call Summit if You don't find the answer, ask 'em to pull one & put the ruler to it, unless they're shipping those direct from mfr. .....in which case I'd call them.
