Radiator doesnt fit please help

Hello, I'm new here and I joined up because I though you all might be the only ones capable and willing to help...I have a first gen 1999 Tacoma with a 2.7 L 4 cylinder pre runner 2 wheel drive automatic. My radiator blew..end caps cracked and won't hold water at all. I've been looking for a replacement however I've looked at 5 different radiators and the specs on them say "18 11/16 x 25 1/2" which is what I need...but when I try to install it was to big...I measured and it was actually 26 1/4 wide...every single radiator I've looked at has the same issue even thought the specs say it's the right size...has anyone had this issue or have a solution...please help and it's greatly appreciated

 

Where did you buy it? So did the bolt holes line up with the core support holes on your truck?

 

There are a few sizes for our trucks. I think autoanything.com had size options with dimensions listed. Maybe give them a look.

I called my local dealershipto find out my dimensions. I gave them my VIN and they verified the size

 

The radiator I bought first was from advanced..but I got the dimensions from the old one...but the new was wouldn't even fit into the engine bay...it was hitting the frame and wouldn't go into place

 

maybe try ebay?

There are two sizes if I remember correctly, one is an inch or so taller than the other.
