Steve,
Body prep was easy, the spray painter did it.
As for your question to Tenrocca: Harrison is lighter. Harrison seems to have better engineered suspension. You would need to check with local engineer as to whether this is acceptable in NSW. Ian deliberately uses parts from production cars as they all meet NSW ADR compliance. There are guys in the NSW club with Harrisons so probably best to talk to them or direct with Warwick.
One of the major advantages of the CR is the body comes off so its easy to install mechanical bits.
There are a lot of guys on this site who have Cr's so the support is good.
One other thing is that I have never heard a bad word about Warwick on this site or any club get together.

Iam in Townsville at the moment for work. Boy do I envy these Queenslanders weather. At least in Winter.
