Are you in Sydney, If you are I'd maybe come around sometime to give you a hand with stuff if you want. Like working on RA40s, have 4 myself(selling one to friend will only have 3... so terribly sad...) Also have about 8 cars worth of spares...
Also have an 18R-GEU(efi head but with carbies cause I can't get my hands on the efi stuff) sitting around asking for a rebuild if you're eventually interested.
Just noticed you're near hornsby, I'm in Beacon Hill, you just found yourself a friend...
