1970 Charger hood hinges

[Charger jUNkiE]

Doing a walk around check on my car and noticed the hinges seem to have a lot of slop in them.  I did some research and found a place that reconditions old OEM hinges.  I heard that the newer stuff is questionable.   I didn't want to send mine out for racon and then wait for them to some back.  Thought I would get a core pair send them in and then swap.  Plus I'd still have the originals.   Looked up part numbers and noticed the parts book has a section on springs too.   My installed springs have a 25-1/4 turn hinge spring.  The cores I received have a 27- 1/4 turn spring. I've checked everything else on the hinge.  The only difference  is the spring size. I'm looking for somebody that's been down this road and knows about what springs are compatible etc. I think the rebuild place is  ricks or Richardson was going to rebuild the hinges. Any reviews from anyone on this place?   Also is there a way to paint these so that the operation of the hood doesn't scrap paint off of the different sections of the hinges or is this life with a Mopar hood hinge?
