Do an images search of the two models to start with and then you can determine if they at least look alike, might just be a chrome accent difference.

The online interchange search (www.car-part.com) does list the truck tailgate for the Trailduster

Motor lists the 1978-1980 Ram pickup/Dodge Ramcharger/Plymouth Trailduster tailgate shell as the same part # 4113262.
Possibly earlier tailgates will work, but I have a gap in years. Google it.

You'll find that the PU tailgates don't usually have the spare tire mount. Yours might have the spare inside, but mine was outside on the gate.

I have a 1975 Dodge D100.

I bought a tailgate from a 1977 Plymouth Trail Duster from a wrecking yard and replaced the shabby looking Dodge one.

It fits and works perfectly.

You just need to remove the tire mount off the Plymouth tailgate.
