I've had the 8 Ball since '86-'87 and I drilled the hole to fit the B&M or Hurst floor shifter for the TH400 in my '56. It was loose on that shifter, but just rotated, it wasn't sloppy. When I parked the '56 in '91 I put the 8 Ball in Mean Green but the hole is too big, and the 8 Ball flopped around on the shifter. It was always loose, and no amount of tape or anything would keep it snug. Back then I was pretty rough on the old truck, with bumps and jumps, and carrying on. One night the 8 Ball popped off the shifter, and it was never allowed to be used again. But I like it, and want to use it again, only thing is I want to be able to screw it down. That said, I was eating lunch just now and thinking about this, and realized there is a Budget Bolt a couple miles away, and they may have the insert I'm looking for. If they do I can epoxy the insert into the 8 Ball, get a thin nut to lock it in place on the shifter, and that would hold it. I just need them to carry the insert I need, and they should, they a wide assortment of various types of fasteners. So I'll take the shifter out of the transmission, and take the 8 Ball along with me, and see what they have. Worse come to worse, I could use one of my 1/4 inch chisels and make the hole a hex, and glue in a fine-threaded nut. Either way that 8 Ball is being used again, and I think I have figured out my solution to do it. Or I can acquire another 8 Ball and start with a smaller hole. Options.
