Super Sedan/Late model Specs

[johnnyq21]

Hi all was wondering if anyone can help me? I'm interested in building a sedan but the only specs I can find is on the luddenham site and there is a few things that they don't mention. IE: construction material, doesn't stipulate material type chassis can be made of, minimum measurements, ok it's got all the maximums but does it have to be 48" long or can I make it 36". I know your probably reading this going "are you really that stupid" well no I'm not I just want to build it to within specs so I have no problems down the track. If anyone can help it would be appreciated.
Thanks. Johnnyq21

Ok now I'm a bit confused no alot confused I just checked WA's specs a little bit more detail but now I have conflicting specs as far as rear driveline/suspension is concerned. LQSS specs State independent allowed diff must be locked, but WA's specs state solid rear axle... Can someone please let me know the best way to go I would rather go independant rear but still want to play by everyone's rules.
Thanks Johnny
