    Joe Curry and I have been having some discussion about 
chassis/commisssion numbers. Was there ever a requirement that SCCA racecars 
have a chassis/commission number? (We understand that the starting with the 
introduction of logbooks in 1972, there was an identification number on the 
rollcage).

    Was there other sanctioning bodies that might have required a 
chassis/commission number on a racecar?
