rebuilding H.B. shocks
 

Do the Hot Bodies Threaded Shock Set p# HBS61161 and High Performance Aluminum Shock p# HBS61184 take Hpi internal parts ie. O-rings, piston disk and shock rod ect.? I know if you bash the plastic ones are the way to go because of the cost of replacement, but I found a great deal on a couple sets of these and want to know what I need to rebuild them.
