Only know this DIY option on a 72 Riviera (Dutch language, but photos will tell the story): http://www.amerikaanseautopagina.com/forum/viewtopic.php?f=8&t=24571&start=210 2 months ago:
Not sure if OPG has them for Riv's but they have them for Skylarks http://www.opgi.com/p/cooling/15816/79/CH27810.html http://www.opgi.com/p/cooling/24328/79/CH28589.html Call them and check if those will work or if they have them for a Riv. Good Luck
