Midget chassis.......

Ok folks, doing some research and I have talked to some chassis builders already but going the extra mile to see what else is out there and available. I need a chassis/driver area that is not only wide, but longer than standard....This is for a 6' 3" person and current car length his knees hit the steering box and cant really move his knees/legs around and needs more room..

Ill try to explain the measurement taken if I can...

1. what is your Inside to Inside measurement between frame rails/Seat area?
   
2. what is your Center measurement from the steering box left side tube, to the inside of lower seat bar behind seat?

For instance my current car inside to inside seat area is 21 1/2", my measurement for center of steering left side tube to the inside of the rear seat bar is 28". this is where I need the length longer and 2" taller cage is necessary..

Chassis builder or people that will help, please measure if you would and PM me your measurements or if you able to build a specific chassis bigger, please send me details and please include what chassis brand this is from and cost. You can email me directly at ronnieandpam01@comcast.net.

Thanks...
