So I searched and I found that a few people recommend a radiator from summit racing part# 1-26221-F What do you do with the fill? Cut it off and have it welded closed or does it fit somehow with the fill neck? I was going to run the contour fan setup. This is going in a 94 miata with 89 mustang 5.0 and t5, thanks.

 

I can't answer your question on the referenced radiator. However the copy/paste below from a few years ago details my approach to the radiator issue. I did have a local shop weld this 90 degree aluminum fitting into the factory inlet on the radiator. With the appropriate trim job it makes for a clean upper radiator hose installation.

"I'm running a Ford specific radiator from Summit, ordered it from Summit's Ebay store and it's a Griffin Aluminum Pro Series Radiator 1-26241-X radiator. It's a 27.5x15.5, two row.‏

If I were doing this again, I'd use a different Griffin radiator. My 27.5" wide (as advertised) is actually 27.75. The extra .25" makes for a very very tight fit. I had to remove part of the radiator/hood latch support bracket and use a big Ford tool to massage the frame rails on each side. Griffin GRI-1-26221-X is 26x16, and GRI-1-266222-X is 26x19". I would use the 26x19 if I had a do-over. The install would go much quicker. Price is the same."

Thanks for the reply your post was the one that I saw the part number in. I would like to get my radiator under the core support/header up against the hood release. I might just have to buy the radiator and get the neck removed or try and find one with no fill neck.

BTW nice clean car and install
