Sidewinder Pin Box Options for a 5th Wheel Trailer with Lippert 1716 Pin Box

Question:

This question is for Michael H., Thanks for your reply, sorry the info I gave you didnt make it with the pictures I sent. I have a 2008 Keystone Montana 2955 RL, i want to replace the king pin with a sidewinder king pin. here are the measurements I got off of the trailer. 2a= 8 3/4in 2b= 2 1/2 in 2c= 2d= 5/8in 2e= 15/16in 2f= 6 bolts each side 3a= 20 3/8in 3b= 29 1/8in 3c= 12 1/4in I believe the hitch is a lippert 1621 or a 1716. The hitch label has a 16 but the rest of the label is unreadable. Have any ideas? Thank you.

Your measurements are almost exactly the same as the Lippert 1716 pin box. Everything is nearly identical which I do expect it to be off by a hair due to tolerances. For a 16K model Sidewinder and air ride pin box combo use # RP61412.
