255/60R15's will fit on the front.
The wheel offset is the main concern.
If you use 15x7 with a 4.25 rear spacing you should be fine.

That what's on the front of this GTX I used to own.
It had 275/60r15'son the rear.




Sorry to hijack the post.
A guy is coming over this weekend to perhaps buy a set of 15x8 AR200S's with 245/50s on them. The BS is 3-3/4". His car is a '68 GTX. Is he gonna have a problem? The car is same as OP's Q, so I figured it was a legit question...
