I replaced my 20" 2-core radiator with this ACP 24" 3-core radiator for extra cooling. The 24" radiator fit nicely into the new brackets which I also purchased from WCCC. The lower hose and both tranny fluid line hook-ups fit exactly the same as the 20". A new upper hose was needed, but I already knew that from watching the WCCC video. I've only put about 20 miles on it, but so far so good.
