To the vertically endowed.... question on mirrors and seats

[big31]

Greetings,

I'm 6'5". I finally have my '31 A truck in a reliable enough state to use it regularly. On long trips the hunched over nature in which I'm driving starts to become uncomfortable and it would appear almost every mirror combination meant for the A, will not work for someone of my altitude.

So my questions:

1. I'm using a '68 mustang rear seat which is 11" from floor board to highest part of the seat. How high are OE seats on a 31?

2. Mirrors, stock mirrors, spare tire mirrors - do not work without becoming a contortionist. What are you using in lieu of stock to see what's behind you?

As always, thank you for any reply.
