it was the same paint as the dash , most were painted in the vans life to mat black but in 1984 (plasitc grill) the suround was grey as the dash! so basicaly 1978-84 satin black 1984-86 grey!
if you look on this photo of a van i had a wile ago you can see the colour matches the dash ,this was original paint! but i think it had faded abit in the sun!
this van was orginal paint at 1900miles you can see the grey!
