I have a 1978 Dodge van that needs rear doors and a bumper. Does anyone know what years will work? I've been told several different things. Thanks!

Some searching online should confirm, but my memory is that 78 is the transition year. Some old (71-76) some new (79-93).

Yes, it is...

You can check your local wrecking yard for interchange info, I know the U-Pik-It here will provide it free.

This will give you any year that will fit and gives you places that have them.

The doors I found only come up with 1978 so it looks like it's a one year only.

Try asking over at the B van forum.

I know 78 had it's own side marker lights too.

So far I've been told up to 1990. There's a 92 in a local jy that looks very simiar. Anybody?
Thanks!

78-92 I used a 92 for parts a wrecked 78 440 Maxi Van I had

I cleaned the floor off in the rear with my race car & trailer & replaced it all with 92 stuff back in 93 or 94
