Hi Brooksie,
G Force are a very similar body shape to RMC. Many folk have been down the search path of which kit? You will as Bernie has suggested get a multitude of replies!!!!
The G Force Mark II is a custom built chassis and there is a Vic member who is just completing his and from what I have seen a very neat Kit to build. If you dont have great engineering skills the Mark II is a very good Kit. Dont know much about the Mark 1 but I would suggest many people do not like the chop and swap chassis. There is a mark 1 with 351 and a 98 RMC for sale in WA from "All American car sales" in WA both cars look O.K. (Check out
www.carpoint.com.au - go to either used car search or dealer search.) Wayne Holland is good bloke as far as car salesman go - I bought my RMC from there.
Other suggested kits that I looked at are RMC WA, Classic Revival NSW, Laurie Bongailas (RCM) Vic (a good kit, priced very well but needs good engineering skills to complete). If you can get a hold of "Australian Classis Car" Mag May 2001 issue 94 or Feb 2003 issue 115 both have a fairly comprehensive articles on the major kit suppliers / builders.
Good luck with your search and welcome to the forum and your journey into cobra life. You will get a lot of information from the gang on this site!
