71-74 Charger B-Body Door Hinge Repair

Hey guys!
Here is my current problem. I can find door pin kits w/bushings, but.. no springs. One supplier I'm aware of sells reproduction hinges but due to a foul up by the manufacturer they're unavailable. My 39 year old Charger has sagging doors and both lower hinges are missing the springs. Any ideas where to source springs,or recommendations as to who to send them to for a rebuild??

On the good side the carb is adjusted, spark is finally dialed in and the car is a daily driver. Well with gas prices a twice a week driver.
The exhaust still needs some adjustment to prevent rattling and some dynamat type material would be nice too. No working radio at the moment. Tho between the flowmaster 30's and a lack of acoustic insulation it wouldn't be easy on the ears.
I have the sansden AC compressor conversion kit to install. Will go either 410 or back to R-12. Being in FL means install soon or drown in your own sweat. 95'F sucks with this humidity and a racer black paint job.

Thanks for your pointers in advance.:rolleyes:
