This is a shot in the dark and I'll look into it further when I get home, but I have a diesel radiator for an '84 Riviera that physically fits in the Riviera, but the trans cooler lines are bigger. If anyone is familiar with what I'm talking about I'd like to know what size the fittings are so I can adapt the original trans lines. I'm guessing they're about a 5/8-18 inverted flare, if so I haven't seen anything to adapt them except barbed fittings or push-loks. I'm open to ideas too! I've checked spec sheets as well and the fitting sizes aren't listed.
Here's the vendor and PN if it helps. APDI/PRO 8010155
