Has anyone used the replacement rollers available from Chevy Duty, Brothers, etc? They look to be all the same, bur vary widely in price. Are they worth a darn and are the "rivets" that mount them metal or plastic? Also, is there supposed to be felt in both the vertical rear AND front channels, or just in the front (on the vent window assembly)? What is the best lube to use on the regulators and the rollers (we live in the Las Vegas desert with no moisture or rust issues, but do have a lot of dust)?
Thanks,
Gene
