70 Duster Parts Needed

Just suggestions here...
You probably wont find a better 40 year old regulater for the drivers door since it is the most used. Those can be repaired in most cases.
The hindge pin and bushing kits are on ebay etc.. , average price is 12 bucks.
Those kits wont come with instrustions but many of us have been there / sussed that. :)
Those fender braces might be found or fabed. Good luck
