Back in the day, the 7.75x14 OE tires were much skinnier and 3.75" BS would work. Today, the wider radial tires need more like 4.00 - 4.25" BS for a 7" wide wheel.
Why they didn't rub on the '67? There could be many reasons. Your front springs may not provide the same ride height as the one's in that '67 - a fraction of an inch could make all the difference.
You could try putting a spacer under your front coils to gain a little ride height if you want to run those rims and those tires on your car.
I have run 3 different tire sizes on my '64 - 205/75/14's, 235/60/15's and 215/55/17's. I can't remember the BS on the 14" factory 6" rims, but my 15x7's were 4.25" and the 17's are 4.625" BS.
No teasing from me, I'm an old guy too! I've owned my GTO for 33 years and still running poverty caps on black steel wheels - same poverty caps fit on the 14's, 15's and 17's...

Hi, & Thanks,
Not to sound stupid, but I haven't fooled with classic cars in about 30 years and times do change, so I have a couple of questions.
1) Due to the backspacing measurment, will I need to change wheels?
2) I'm guessing I would need to change tire size (tires are essentially new), and if so, do you have a recommendation?
3) Will I wind up having to change both tires and wheels??
4) Any other recommendations?
Man, I love those tires/wheels on that car....... But I guess ya gotta do what ya gotta do!
Thanks for any insight, recommendations, or changes!
Geez, this little investment is gonna get expensive fast!
