No one seems to make one for the 81-92 Ram 4 door truck.(Column Auto)
Could it be they are calling this an "extended cab"?
Could I use a set for a Ramcharger/Trailduster and expect it to fit reasonably well?

Any leads appreciated.

Thanks Moparts for the post

The 4 dr Dodge Ram is known as a crew cab



There's much out there for your rig, I looked at most of the major carpet suppliers,...just regular cab and extended cab,....there's only one vendor NIFTY CARPET,....I've used a NIFTY carpet, a cut pile in the past for my extended cab Ram, it, surprisingly, was very nice,....your best off ordering it thru www.jcwhintey.com the part number for the NIFTY brand carpet for 4 dr pick-ups is QB21985G, you'll need to supply them with more information at the time of your order regarding the year,make,model, etc,....the price range is $135-$535 USD depending on application,....but Dodge applications are covered from 73-98
