I can only read a partial Bilstein shock number of:  F4-B46-20 . . . . .
 
What is the shock model # for Bilstein and/or Koni replacement?   2 in front - 4 in back?
After market shock dealers ask what the frame model is for this rig.  Can't find that info and Monaco can't help?  What is it?
Thx for the help.
