Barracuda window regulator help

[Kudabill]

I have a 1966 Barracuda and need to rebuild/replace the back roll-up window regulators. It takes two hands to get them up or down. All I am able to find is a rebuild kit for 67 and up. Does anyone know if they are interchangeable, at least for the rollers? Or, does anyone know where I might be able to buy some already rebuilt or some that might still be in good working order? Any advice would be greatly appreciated.

I would remove the regulators one at a time and see if you can free it up. I'm sure the grease they used back in the 60's is just gone hard and the parts just need to be freed up. It could be a set-up issue as well, and they could use some adjustment. Only do one side at a time as minor as it seems they are tough to get back together.
