Firstly, how much priority do you place on a correct (ie: authentic to the original) appearance, dimensions and stance? If not very much, there are a number of manufacturers that have stretched and bulged the shape to varying degrees that may or may not make a big difference in cockpit space. Backdraft and Lonestar among others fall into this category.
If you want a Cobra that maintains the authentic outward appearance, most of the major manufacturers - Kirkham, ERA, Unique Motorcars, Hurricane, FFR (MKIV model), etc - will build you a car to suit your height. They've all done it before and have the required mods down to a science.
Pick a manufacturer you like and give them a call. You can have it any way you want it. No need to settle for a less desirable car because of your height.
