Shimano HT2 MTB crankset

After a Shimano HT2 MTB crankset with the following specs:

1. Used - read lower budget
   
2. LX/SLX/XT (might consider Deore)
   
3. 104 BCD, don't need any rings or BB, just the arms.
   
4. Ideally 170mm
   
   

Something like SLX m660 or XT m770 would be perfect.
Thanks
