Im looking for magnetic bit shafts for my Armstrong silent ratcheting screwdriver 66-583 and stubby 66-582. Gearwrench is the only brand I can find that makes what Im looking for, however, Im not sure if thats the correct fit. Any suggestions? Prefer non Taiwanese/Chinese. I think Vessel might and maybe SnapOn bit they cost more than the screwdrivers.
Magnetic Bit Shafts for Armstrong 66-583?

I left this reply in your ratcheting screwdriver thread as well, I hope this helps.
Cripe has Armstrong magnetic extensions with part numbers in near succession to your handles, but they have hex male ends, not square drive male ends like on the gearwrench or snap on magnetic shank/bit holder. I noticed you said you are not sure if the gearwrench square drive would fit. You may want to double check if the female end in the Armstrong handle accepts hex or square drive shaft. Because I found a Spec Tools driver on ebay (sold by Cripe), and it looks almost exactly like the Armstrong handle (more like my blue handle), and it takes hex male end, not square. If your handles have a hex female like these Spec Tools, these Armstrong extensions looks like it could be what you are looking for. And they have 5.5" extension for $5 and 9.5" extension for $6.
Spec Tools, check out the handle and shafts:

Yeah, so glad it worked out. And the 2 lengths are totally worth getting.

Are the female sockets in the screwdriver handles 1/4 hex or 1/4 square ?
