There are a number of adjustments that you can make; an E-body has lots of room. I'm 6'6", big, and that's one of the reasons that I've stuck with Cudas & Challengers over the years

- make sure that your seat tracks are going all the way back and are not getting hung up near the end of travel

- you can adjust the angle of the seatback by moving the catches - even elongate the slots if you need to to get more room

- spacers: thicker spacers under the front seat track studs and thinner ones under the back will also help with driving position (though I've not had to do this personally

- Tuff wheels do provide some extra room. 5 minutes and 3 nuts later and you can swap back to a woodgrain or rim-blow for show purposes
