Is FLM10800 & FLM10900 chassis braces the same?

Ok the stock Traxxas chassis is slightly longer. This is because the stock chassis has little step ups in it so that it can sit on top of the bulkheads even past the flat mounting spots in the bulkheads. As far as the distance between the actual bolt holes in the chassis for the bukheads from the front and rear bulkheads the chassis's are the same. The only other difference I saw, is the trans in the stock chassis sits further back. Ive seen people have to trim the extra material off of the stock chassis when installing aftermarket bulkheads. I can upload pics to help you better understand my explanation if needed.
