Thank you very much for your concern but I can assure you that I was never worried about any of the above points. As I have no intention of buying a chassis from you as ive already built my first one and its in my workshop with an engine/g/box fitted modded brackets to fit 7.5" diff and the complete front suspension on it too.
As always my comments are always meant to be helpful and hopefully knowlegable. it would seem you dont know what a sierra engine mount rubber looks like but im sure you will find out
do you live anywhere near poole ,dorset? I would be happy to show you one lol
