Hi, I am looking to replace the radiator due to a leak. I have been looking at Champion MC284 (4 row core) as well as the CC284 (3 row core). I am leaning towards the 4 row core unit, however, their website says that "Due to the thickness of these tanks your saddles may not fit". The 3 row core unit is apparently a direct fit.
What does this mean in practice? How much of a modification would it be to install the 4 row core? I'm not too dogmatic about modifications from stock if they can be easily reversed or are in an inconspicuous spot.
Anyone with first hand experience installing either of these rads?

Thanks!

Anyone? Would appreciate some input, even if the answer may seem trivial. Still learning Oldsmobiles.

You can buy new 4 core radiator saddle's. They are spot welded in, so not a huge task to remove and tack weld the new ones in. Some guys will just bend the 3 core saddle's apart to make the radiator fit.
Don't know about those new radiators you listed.
