hodson, Blairs advice is spot on.
The RCM should have no problems as far as chassis engineering. It would only be any engine the seller wants you to pay for that may be a problem.
Check with your engineer before parting with cash for any engine the seller wants to sell you.
Also do an advanced search on the Australia Forum in here and you'll get heaps of threads to read.
and.....
Take no notice of that Blair fella....his car wont be fast enough to pull the skin off a custard.
Not till he gets it going that is.
