75 Scamp, oversize wheel options?

did some test fitting today. The 76 dart should have the same wheelhouses right?

I tested 17x9 'stang rims and 16x8 conquest wheels.

17x9s will no way fit the stock wheel housings. I'd have to cut.

the 16x8s I have will fit, but only if I use a stock 8.25 rear (which I did locate for $150 at a jyard)
