The Great Pumpkin - '71 Duster

Also got my Griffin aluminum radiator yesterday. This thing is impressive. The tubes are 1.25" It looks well made and way lighter than the 26" brass/copper one that was in there originally. Unfortunately, there's a few issues with it. I'm OK with that, but it's just more stuff to deal with.

One; the original fan clutch is now too long. I researched and now know that the Hayden 2765 should work in this situation, so I have to order one from somewhere. They're relatively cheap on Rock Auto. My local parts store told me $75. Screw that.

Two; the beat up 26" fan shroud obviously no longer fits so I need a 22" one. There's a flange on the outside of the core to mount the shroud, just need to find the right one. Never realized how expensive shrouds were. I've read the repros out there tend to warp so I'm on the lookout for an OE one. Hope I can find one this weekend at ETown.

Three; the mounting brackets on the rad. don't line up with the original cage nuts on the support. Might have to waller out the holes a little to make it work. This is one of their direct fit radiators so I'm not sure what happened here. Might put in a call to Griffin about this and see what they say. Probably not worth sending it back over but it's a little annoying. I may just have to look at it again.

Four; the overflow spout is pointed towards the driver's side but it was originally on the right. I need to be careful with how the trans cooler lines are routed to avoid interference with the overflow bottle. I looked at an RCI catch can which is shorter and would probably work.

Five; the hose outlets are now closer to the engine so I have to shorten the hoses so they won't kink.

And when I went to stick the new cap on, the bottom of it sliced my finger open and I was bleeding all over the place. Grrrr...

Overall though, I'm happy with it. I guess I just had it in my head that Griffin was one of the better products so I went for it. The weight savings is also a big plus.

Pics of it mocked up and burly cooling fins and cap flange.
