Really - did you ask IPSCO directly? Mark Johnson at IPSCO made my lower aluminum cross brace (and the upper) to my excact measurements for my pushbutton car. No extra charge - I payed $75 each for two. I think that might have been the prototype he's (and Dennis) is selling now. My measurements were also a little off compared to the production cars (if I remember a little narrower) but he corrected that and the fit was perfect.
I bought quite a few parts from him and most were custom measurements.
