Finally made tire & wheel decision!

Okay...the 15x6 are on backorder until June and to make matters worse, they each cost $52 more than the 15x7.

For the front, can I simply use the 15x7 wheels (with the 4.125 rear spacing and 3mm offset) with the 215 tires?

Will I encounter any clearance problems? Any issues when I switch over to factory '67-69 (sbp) disc brakes and sway bar?
