Can I run these tires?

Try (74 Hemi Dart Sport )

Here is what I found on your posts in that thread.

"Steel with hinges , Weld rear rim sku # 96-512210 15x12 x4.5 lug pattern with 5.50 back spacing , sku # on fronts 96-56208 15x6 x4.5 lug pattern with 4.50 back spacing, may go thinner on fronts, but don't want to get to skinny with that Hemi hanging out there."

Did you do a spring relocation and a mini tub?

I already have the spring relocation kit and the mini tub doesn't look to hard to do.
