Remember a couple of weeks ago we were talking about ignition distrib. points ? (link below)

Came across more info on the screw type lead attachment (versus the clip type), in the Sept-Oct Chev Service News, describing changes for the 1970 model year. To quote ... (added caps are mine).
" ... an internal shield is incorporated into V-8 distributors on all models EXCEPT THE CORVETTE (?). The shield encloses the points and condenser to supress signals which cause radio static. Replacement points for 1970 Delco distributors equipped with internal static shields must be of the clamp type lead attachment such as those installed in PRODUCTION. Due to the space limitations between the points and the shield, a screw type lead attachment could interfere with the shield causing the lead to short to ground. Additionally, an insulating tape is installed in production on the inside of the shield adjacent to the the lead clamp to protect against intermittent touching of the leads to the shield. This tape should not be removed ".
I can't remember if my new '72 Corvette had the clam shields or not
. Guess it makes sense that if the C3's had a top and surround distrib shield that they wouldn't need the additional shields. But I'll bet they still used the points/condenser breaker plate with slots for the shields.
