Well after lots of research I have made a decision on what to go for donor wise.
I read that some of the locost boys in the US and Australia are using Toyota Hiace van front uprights which I an get easily here.
Also read that some of the mk2 escort racers are using the rear axle from Toyota hilux 2wd or toyota Hiace vans as they are about the same size
So my intentions are to use
1. Toyota Hiace front uprights brakes etc.
2. graft a Ron champion style rear end on a Haynes chassis with a Toyota Van live axle and brakes .
My only concern is what ratio to use as most of the hiace here are diesel.
any comments welcome .
