Torker Dx cranks(the shorter ones)

I’ve got a 24" Torker DX and I’m looking to put some shorter cranks on it so, I’m in the market for some cranks off of a 20" DX. Unless, there are some other cranks that will fit on the DX hub? I just really don’t want to have to fuss about with changing the hub and getting bearing adapters and such.

Condition; ridable.

I’m changing the tire to a hookworm and using it to putt around town in and the long cranks are killing me for commuting.
