What service is missing on your restoration/repair journey?

There are excellent services (members etc.) out there to help us DIY mopar lovers from gauge rebuilds to suspension kits and aftermarket parts. What I want to know is what is missing to support us? Or what is soon to go extinct? Some of the best people I know to restore parts aren't "spring chickens" and once they are gone, the service is gone. So, I am looking to find what is needed or near extinction so I can plan appropriately and maybe start the support myself in my retirement.

Just looking for your experiences and what you fear is soon the end of to keep mopars on the road.

Thanks
