MRX4XXXX:
The slightly revised Protoform P909 has been in production since mid Nov. 2010. It still has the original part #1504 marked on the mold. The body was re-submitted to EFRA and they did not require a new EFRA number to be put in the mold because the changes were so minor.
There's a strong possibility that the distributor/dealer network has the un-revised bodies in stock - and will for a period of time. The best way to ID the revised body is the small center fin at the rear spoiler.
*Note: the unrevised body is ROAR/BRCA/FEMCA/FAMAR etc. legal and will work equally well in Non-EFRA sanctioned racing. The changes were made because of a minor 2011 rule change in side dam height required by EFRA (IFMAR).
