I recently ordered a Clancy radiator on Ebay for installation in my '71 Int'l cub (s/n: 238320 J). The replacement radiator was about 1/4" shorter then the existing unit. Due to the shorter height installation of the side channels was not possible.
The new radiator on the left is 13 1/2" between the arrows. The old radiator on the right is 13 3/4" between the arrows.
It appears that IH changed the radiator with the change to square hood. Clancy does not make the newer version.
Has anyone come across this issue and/or knows of a solution? One possibility is to fabricate a 1/4" plate in the shape of the gasket and install between the casting and radiator with two gaskets. 1/4" would need to be removed off the top of the side channels.
I went out and measured my Clancy replacement radiator, and it is 13 1/2 inches just like yours. I also measured an international radiator (I think from a 50s cub)and it measures 13 3/4. I don't have the original 49 radiator here at the house, but I would bet that it is also 13 3/4. That being said, I didn't have any problem with the hood supports fitting on the Clancy radiator. I looked and there is 1/8 to 1/4 inch clearance between the top of the supports and the bottom of the tank. I did have to replace the Clancy filler neck with the original, as it was about 1/2 inch shorter, and the cap hit the hood. Maybe someone else knows of a change in the hood supports.
Is the Clancy made in Ireland? I have seen some mention of of Irish radiators but have not seen one except in photos.
If the side supports do not fit, could the bolt holes be elongated? What about a bottom spacer under the radiator about 3/16 thick with a gasket on both sides? That would raise the radiator about 1/4". Neither aluminum nor steel would be ideal material for such a spacer, but either would last for several years. Steel might be the better choice since electrolysis is quite vigorous if aluminum and copper should be in actual contact.
I have a Cub radiator made in China some number of years ago, but have never installed it.
Had to replace the radiator in one of the cars here and the aftermarket replacement is from China. Looks a bit different from the original but it fit and performs perfectly.

Luck favors those who are prepared
There were some changes to the neck along the way. I found it when I went to install a square hood on my 65 Lo Boy, couldn't close the radiator cap without scratching the paint. The hood had a steeper crease than a 'normal' square hood. I had a radiator shop extend the neck on an aftermarket radiator (got the new one from TM). The whole thing puzzled me.
It seemed to be the difference in the neck, but could be IH changed the overall dimension? I noticed my 71 has a similar neck to the one in your picture, taller than the others.
The whole front end of the 65 Lo Boy had been replaced, probably including the radiator, but not sure when the radiator changed. The bolts didn't line up with that hood, so I used a different hood (probably the one that was on the Lo Boy to begin with).
The 71 with the original radiator, notice the cap is way above the hood:
1971 Cub (Rufus) 1950 Cub (Cathy) 1965 Lo Boy Fast Hitch (Nameless III) 1970 Cub 1000 Loader & Fast Hitch (Lee)
I don't think a spacer is going to help because the side supports go ON TOP of the radiator flange.
As I understand the main issue is that the side supports won't fit in between the flange and the top tank.
The Clancy radiator is made in Ireland.
I think steel would be the best bet for a spacer.
The side channels would have to be cut down 1/4 or so in order to fit the shorter radiator.
You would have to trim the bottoms of the side channels or also move the welded nut for the hood brackets. Seems like it would be easier to just trim the tops as needed to clear the top tank and get the filler neck extended.
Is there a problem with the fan shroud too?
Yes, the 1/4 would come off the top.
Good point about the shroud. The hood may be impacted too since the welded nuts will also be 1/4 inch higher.
I'll have to mock it up and check if it will all work.
Pain in the neck. Seems crazy that ih would make the radiator 1/4" higher to accommodate the square hood styling change.
Interesting, I changed the radiator on my early '79 using a Clancy as replacement. I DID have to grind down the tops of the radiator supports for a proper fit, however, on reassembly everything fit properly to include the radiator cap. The only thing I didn't like about the changeover was the orig. had a 4 tube wide core and the replacement only 3 tubes wide
Easier said than done in most areas. There aren't many/any good old fashioned radiator shops around anymore that will do that sort of work. All they want to do is sell you a whole new radiator.
I went to the Links page on the Clancy Radiator website and it provides a link to the A&I Products website
I went to the A&I Products website and found the listing for the Cub radiator. That A&I Products listing shows the same drawing as the ebay listing and provides the dimensions for the drawing as well. The drawing dimensions show the core height as 13 3/4".
I might e-mail Clancy at the address listed on their contacts page email@example.com and ask about the discrepancy.
Well, not sure what to say .... Multi Rad here in town recores all kinds of rads from reefer units, trucks, off-road heavy equipment, cars and Cubs. They even have the pressure testing plate for the Cub rads. Multi Rad is also a Gas Tank Repair facility.

are a couple of hits, there are more on the google page. Hopefully that will help. Unfortunately I am not all that familiar with NY State so not sure how close these are to you.
