go to a dealer if you dont want to go to a private seller
or alternatively post up where your from and im sure some of the local lads will be more than happy to help you out.

I'm 6' 3" and no probs in a SW20, a T-bar should give you an extra inch but as people say, plenty of options including seats/seat spacers. And driving position will also be a big factor, telescopic steering rack will also help. Is it true only imports got these???
 
Used to drive a sunroofed AW11 too, but probably still have the crooked neck to prove it. Where there's a will there's a way.

Get a Spyder, I'm 6'4" and over 120KG and fit easily, and it's better than a T top, it can have no top.....lol
