I have a brand new set of SC36AA for $70 shipped to your door if interested.
The new TPMS from Dodge with replaceable stems pn are
06-07 56029526AA
08+ 56029527AA
The stems are $5 a piece, I still recommend Orange TPMS over OE ones due to the stem being cheaper to replace and they swivel so if you have aftermarket wheels they seat better.
