Door Glass Mechanism: recommendation needed for a shop in Long Island

[70Challenger440]

I have a 70 Challenger RT. It's a very nice car but has always had door glass issues, (especially rolling them up and it has gotten worse over the years). I decided it is best to finally get the Achilles Heel of my car fixed  right and professionally. All the metal parts and bolts are in place so it just needs to be  completely cleaned/refurbished  with all those repro plastic parts and adjusted well.

I am having trouble finding the right shop. Typical places that do auto glass run the gamut of inexperience with classic cars to saying they wouldn't touch the job with a ten foot pole. Meanwhile Resto Shops consider it too small of a project. Can anyone recommend a business with experience on Long Island NY that they think might consider taking this on? Thanks.
