Steve, I don't know the answer to your question but I have three suggestions.9 seconds said:
1. Take a good nose-on picture of one to a graphics guy. Those guys are good about looking at the relationship of stripes to hood features to determine width.
2. E-mail one of the sellers of the VCA SRT-10s on Ebay and ask them for the measurements.
3. Put a post up on the VCA site and ask one of the winners to send you the numbers.
BTW, was good to meet you down in Baton Rouge. Bob
