Just a thought ...might Aussie Heralds have bigger radiators ? certainly gets hotter over there !
If your body is sitting lower thats going to throw lots of things out ...I left little scars on the rear of the Sammio indicating the section that needed cutting out and with the little shelves on my bulkhead sat flat on the stock bulkhead , the cills should just about wrap around the outrigger siderails ....it made it tricky to get it wrong ...but I don't know how Mike did his to aid getting it right ? I would guess that the cill location would be about the same ..
I googled some images and found this one showing a Miglia on a build blog that has had the body fitted and it shows quite clearly the line of the boot outrigger and distance between the top of tyre and wheelarch with a stock rim ...maybe you can get some clues from that ?
