396 Starter heat shield ...1st design, ...vs. 2nd design???

[KevinK]

  It is my understanding there were two designs of the starter heat shield from the mid 60's to early 70's (on a number of chevy's, ...including Camaro).
   Anyone know when the approx. swithcover was from 1st to 2nd design?  ...I am trying to locate the correct one for my (04C) built '68 Camaro (396).
 
   Thanks,
               Kevin
 
   ...I believe the 2nd design is slightly larger than the 1st.

Kevin,

The starter heat shield (P/N 3954224) wasn't installed from the factory on the 1968 Camaro. This didn't start until 1969. Not sure about 1st or 2nd version.
