22" vs 26" Radiator Question:

[A383Wing]

As an aside, don't think that opening up the passenger side
bulkhead the extra 4 inches will work.

Both sides of a factory 26" bulkhead are different, at least on our 70.
If you do one side only, the rad will be not centered in front of the engine,
leading to the factory shroud hitting the original sized fan.

my 70 had a 22" radiator....I got an aluminum 26" one and it bolted right in on the drivers side, uses the same mounting bolt holes. All I had to do was open up the passenger side core support and make two new mounting holes for the radiator mounting bolts. New fan shroud bolted right up to the new radiator and the fan sits perfectly in the shroud.
