US Mag Indy wheel question

They show a 15x7 with a 3.75 backspacing available with a small bolt pattern. I’m gonna venture a guess this will fit fine on a 67-69 Dart? 15x7 would be great but I wanted to make sure and if anyone else has ran these on that era of car.. I’m thinking a 225 or maybe even a 235 tire would work? I’d rather have a bit of sidewall bulge over them being too narrow for the wheel.

Also they take 60° conical lugs which I think are pretty standard. Being these are LH studs on the left side (from factory) I’ll need to double check before ordering lugs.

If anyone has any photo examples, that would be great too. My favorite all time wheel for cars of this era is the old slot mags and I was stoked to find out that they make them in SBP. At first I thought I was gonna have to do with cragars again since they used to be a cheap wheel option… not anymore. Indy mags being cheaper now is the icing on the cake..
