Re: Will these fit a 69??
Direct answer - NO. Now the rear 17x9.5 with the 275/40 tire can be made to fit in the rear with the correct size adapter (bolts to the hub and the wheel bolts to the studs on the adapter which can be ordered in the thickness you need. In the front you can get a 245/45-17 on a 8.5 wide wheel (those wheels come in that size) with the correct adapter to work. The 315s will not fit at all unless you mini tub. Do a search on adapters and spacers you will see lots of info on this. Also keep in mind "good" adapters that are hub centric are not cheap - $200.00 or better. You can find them on Ebay also. Hope this helps.
