There’s a forum for Caminos called ElCaminoCentral.com. Currently a member is parting an ‘87 and another (I think in Canada) is parting several fifth gens. Patrick
I have lots of 59/60 Elcamino original pulls from my Roman Red in silver guts farm truck and parts one myself. All bed trim,side trim,cowl,headlight surrounds,hood trim etc will never use it all but have $ome in it if you know of anyone in need. Will swap for Buick items also. Thanks Fritz
