Wheel Bolt Pattern: 5x4.5 or 5x4.75

[CTX-SLPR]

Howdy,

Still picking away at my '64 Riviera and it's time to start buying mockup parts. I don't have the budget to buy custom parts to get around the fact the rear suspension has a Nissan 5x4.5in bolt pattern and the plan for front is C6/7 front hubs leaving me with two different bolt patterns. Since one needs to be redrilled, which is going to have a better selection of off the shelf wheels as custom units are almost certainly out of the budget?

Thanks
