I'm running P255/60/R15 BFGs on stock aluminum wheels on my '77. They only slightly rub on a frame bolt head in front of tire. This only happens when I am turning tight to put car in garage. mds...
235's will be fine. I did quite a bit of research before I bought my tires and it is generally agreed that 235/60 -15's work on the front and 255/60 - 15's fit on the rear. That is what I ended up buying. I've had no problem with rubbing.

When GM offered the 255/60-15s as an option they slightly trimmed the the leading edge of the front fender and the the bottom corner of the rear of the front fender by the rocker. Check out a '78 Silver Anniversary Car with the 255/60s to see what I'm talking about. With the 235s you won't need to do that.
If you have the Corvette alloy wheels, you can run the 255s. A 245 is a better choice if you can find them.
The 255s on the Rally wheels will rub the frame but that is only at lock, so that isn't really an issue. In some corners, especially with a dip like driveways or side streets, you could rub fiberglass on the front.
On the rear, you just have to check that the inside tire sidewall isn't rubbing the emergency brake cable bracket on the trailing arm. Some tire profiles will clear and some will rub. The alloys have a slightly greater offset and don't rub the bracket.
A lot depends on how your car sits. If you have new springs, and it sits high like many of the rubber bumper cars, you have less issues on front than if it sits low like the '68 to '72 cars.
Now about getting old, you need to avoid OT. They will help you so that tires don't matter.
