Well guys...look like the next step has happen. Guess Koyo discounted them and they had sent me the WRONG radiator. IT was neither r1440 or r1977 models. This knew model had a Part number V020311 (32mm). I'm not paying 285 for this size. So I will be exchanging and hope I get a FULL refund do to website error with their dist. koyo.
Now to try to find old stock to get that 52mm. Can't believe no one else makes em this big any more other then Mishi which s a TAD smaller. I'm almost thinking going Mishi but I don't know. Anyone selling the r1977 stock still for sure?????
