Thanks for bringing this post back to life! If I was going to drive the car hard, I wouldn't even consider belted or bias tires, but it is a fair weather cruiser, and with 2.76 axle it could use the help of a low traction tire to at least make a little noise!
I'm only 3 points shy of 100 now and the tires should be good for at least one. All the 100 point cars in the stock class have original or repro tires (depending on if they are trailer queen or driving show cars).
Seat covers, running clock and correct power antenna mast should take care of the other two points.
