Craftsman screwdrivers (bit holders) have the same cap. They're more plentiful than S-K. See more of them at swaps & sales. The tough part is deciding which one to keep. You'll always be at least 1 cap short. Some Snap On & Mac will also work.Mine are similar, just a bit longer. Model # is 73517 but is no longer visible. Picture wouldn't help.

Just out of curiosity. I'd like to see a picture or two of that solution.Hi Guys, sorry for the delayed response. I've been out of pocket for while.
However, I found a solution. I reamed out the hole nicely and whittled a joining biscuit into shape and glued it in.
Looks nice and it works.
Thanks for your input.
Link doesnt work. Try this, below. Looks like 2.99 each, with standard shipping running $7.99 (even for a few).
Thanks for fixing that.
