The rear is an uncut width 65 B Body housing from a Belvedere.
I ordered axles from Cass at Dr. Diff with green bearings so that I could use the Wilwood disc brake backing plates.
The wheels are 15" x 9 1/2" with 5 1/2" of backspace. They are Summit "Vision" wheels and are on their website. They look like Weld Drag Lites for about 1/3 the price and they are heavier than Drag Lites.
Springs are Superstock 002 and 003 and have been moved back 3/4". The front perches have been flipped upside down to lower the ride height down some. There are sliders at the rear rather than the factory shackles.
There is about 3/4" from the inside bulge of the tire to the side of the leaf springs.
Here are the pics...
