Hey! A fellow Tulsan!
The original wheel base is 90". There is a manufacture that is producing a Cobra replica with 94.5" wheel base, I forget who it is though.
I actually think there is one that makes a 96".
Another thing to check is the diameter of the steering wheel. 16" steering wheel can be alot more cramped than a 14".
One more thing is the seats and how the rails are designed. You might be about to get a thinner padded seat with lower profile rails.
