Technical please help me identify these

I picked these fenders up thinking they were off a Chevy truck from mid 40's. Any idea what they are really off of?

 

Late 30's mopar.

 

37' Plymouth.http://www.jalopyjournal.com/forum/threads/1937-plymouth-build-thread.961312/

 

I don't think late 30s mopar, unless truck. Cars edge revel is wide at the bottom back.

 

I noticed that to. The bead at the bottom doesn't roll all the way too the back of the fender.

 

I thought they were MoPar, too, but the bead is not wide enough.

 

'37 Chevy pickup

 

thanks to all who posted. I've been looking but no luck on a positive ID until now.
