Pre-Bent Brake Lines

Hello All,
Thanks for the overwhelming support in finding the lines.
Lots of good leads.
Now to question two.
"looking for info on a rebuilding kit Or does any one provide a rebuild service for the proportioning valve.
Is there a source for new OEM type proportioning valve ? (not cheep china type)".
I see in Dr Diff they sell a Repo type valve. Is this the cheep china type?
I here that the china ones are junk.
Any comments will help.
Happy Mopar :)
Thanks in advance.
