Anyone know what is the material on the door arm rests?

I think it is pleather, like on the seats if they are not leather.

 

Buy new / used ones from AllMag.

Mine are just a black fabric.

 

Thanks for the link Dave. That's a pretty cool site.

 

Yeah Dustin and those guys at ALLMAG are awesome and I have used them several times.

They can get you almost anything.
