Goodmark Accessories

Roof Rail Weatherstrips by Goodmark®, 1 Pair. This is an aftermarket part that replaces factory OE #MMPRR5020M, 840314109217. Roof may not come readily to mind when you think of body panels that might require replacement on a classic or muscle car, not like fender or quarter panel. But if the roof on your classic is damaged beyond repair by rust, hail or falling objects, Goodmark has the replacement roof skin you need to make your car whole again.

  • Faithful reproduction of the original part
  • Highest quality sheet metal parts available
  • Designed with the latest software and manufactured using modern tooling
  • The same dimensions as the original factory replacement part
  • The same gauge sheet metal as original equipment
  • The largest supplier of sheet metal parts in the GM Restoration Parts Program

Roof damage may not be as common as rusted through quarter panels or dented fenders, but some vehicles were known for certain kinds of rust problems, and a severe hail storm or a falling tree branch can really cause destruction. Instead of being forced to try to repair such damage or piece in a used panel, Goodmark has the correct sheet metal to restore your roof to original condition.

Restoring cars isn't just a business for the people at Goodmark, they're also car enthusiasts and restorers just like you, and they wouldn't make anything they wouldn't install on their own cars or trucks. Each roof is CAD/CAM designed to make sure it exactly replicates the original part, and then it's manufactured with the most modern tooling. Each design is test fit to make sure it looks and fits perfectly. Many Goodmark parts have been approved by the manufacturers of the original equipment and are licensed to be sold as genuine replacement parts.

Along with roof panels and roof brace kits, Goodmark also has the roof rail gutters and roof rail weatherstrip your car needs to look like new.

Goodmark® was founded in 1991 by car enthusiasts, restorers and collectors just like you. They recognized that there was a need for quality restoration parts, especially sheet metal parts, if the restoration of our beloved American classics was to continue. Since that time, Goodmark has created a complete line of sheet metal, trim parts, and accessories for popular cars like the Chevrolet Camaro and Ford Mustang, and for previously difficult to restore cars like the Dodge Challenger and Plymouth Barracuda. Goodmark uses CAD/CAM (computer aided design and computer aided manufacturing) software and modern tooling and manufacturing techniques to create parts that are identical to factory original for perfect fit and finish. Quality parts tooled and manufactured by Goodmark are enabling many more American classic and muscle cars to return to the road, looking just as fine as the day they rolled off the assembly line.
