Size (It matters)

[stevedor]

Hi all. Newbie here.
My wife, bless her, bought me the Build Your Own etc book for Christmas and I am seriously (there's far too much money in the bank anyway) considering it. It has been an ambition for years and I now find myself in a position to do it.

My question is this; I am 6'4", and 18 stone. Will I build this only to find I cant sit in it? Is it feasible to build a "wide bodied" version? Not to mention a "long bodied" version to go with my wide and long body.

When I say "My Question" what I really mean is the first of probably a long procession of stupid and boring questions. I apologize now.
