I moved from a Champion 22" rad (factory 22" rad car"to a 26" cold case rad and it dropped in. I think It was missing the threaded inserts on the top passenger side so I used a nut on a bolt but it was shocking how easy it was to change to. NOW that extra few inches of rad is NOT going to get air to it unless you cut away at your rad support to open it up. If that being said moving a modern 2 rows of 1.25" tubes is a HUGE improvement over an old stock unit or heck even a several year old 3/4 row aluminum.
