Mopar Performance does sell these mini starters, but a better choice is your local ADVANCE AUTO PARTS or AUTO ZONE, they are the same, but they cost less money.
Order a starter from say a 1996 DODGE RAM 1500, I paid $140 for a brand new starter, they do have reman starters for 121.00. Personally, I would only buy a new one, I have had too much trouble with reman starters and alternators.
This starter will fit any mopar engine ( slant six to the 426 Hemi, but not the 4 speed HEMI, The 4 speed HEMI uses a " Direct Drive Starter " I don't know anyone selling these starters, at this time
