On EBay, they list 70-71 Duster. Is the rad support the same on the 70-75 Duster’s? Mines a 73. Also, will a stock mechanical fan still have clearance with a 3 row? Thanks.
In my 68 Barracuda I believe it would.
As said,I run the factory 26" 1973 318 A/C rad, with it's matching shroud. I have no idea how many rows are in that thing. I run a factory 7-blade fan on a thermostatically controlled fan-clutch from an early 2000 Ford pick-up. The fan does not even enter the shroud, being at least 1.2 inches short of where people say it should be. I haven't gone out to look, but I'd guess there is nearly 2 inches between the rad and the closest part of the fan assembly. I'll try and remember to go out later and look, after the snow melts off the hood,(we're expecting a chinook to come thru here for the next day or two.
If things change, I'll add an edit here
EDIT
I hate getting old, hang tuff, the above is not accurate
OK
I see the rad is a 3 row already and it's not a 73. I don't recall ever upgrading but apparently I did. The PN is 3781721 which might be from the 75Dart I once had. And the 7-blade is in fact inside the shroud now. And the distance between the rad and clutch is 1.5inches, and the clutch is the closest thing to the rad.The tubes appear to be 1/2 inch long with nearly as much space between them, and man do they look plugged up! lol.
So the answer is yes, a FACTORY 3-row fits.
