463 radiator in 460 with m117

Hi all,
hoping for some advice. my 500 ge transplant (into 460) has made a lot of progress in recent months. the m117 now sits in our 280ge, i have a new custom twin pipe exhaust with extractors. my next problem is the radiator. the existing 280ge one is too small for the 5 litre and the 500sel ones from the 126s are not going to fit the Gwagens engine bay. i have found the part number for the 500ge radiator is 463-500-12-00 which actually seems to fit all 463s! the problem is here in australia i would have to order the radiator without having seen it and it might not even fit!!! i thought i would email to see if there is any chance anyone could take some pictures of your radiator, or simply measure it top to bottom and side to side? i do understand if its too much an ask!
any advice you have would be really appreciated.
best regards for the new year
