Ahoy !
Saw your request and having a V8 TC 'basket case' I was faced with a lack of radiator. Quote for a one off was £400 so did some research and found this on EBay 152805278858
Have ordered one, it is on way. The original vehicle was a Honda and covered powered output up to 150hp and being alloy it might do the job? Chinese but am sure they know a thing or two !
My cowl however has been fitted a little higher than standard and the new rad has 40mm clearance as is. You may have to lean it a bit to get in. They have a range so may have one smaller. They give core sizes and overall but this includes spigots in thickness.Good luck !
Am after throttle cross connecting linkage and levers ?
