Mid-year Ignition Top Shields

[Martin M.]

I am trying to organize the pile of parts, so my son will understand what is what, in case I do Barb and I in during one of our high speed runs. I have a number of ignition top shields that are all Mid-year, but I am not sure of the years. Can anyone help, given the following descriptions?

2 Nylon top rivets, I believe these are early '63
3 Metal rivets, not early '63

Are these any other identification marks that can ID these further??

Thanks

2 Nylon top rivets, I believe these are early '63 (I believe these are all 64 to 67)
3 Metal rivets, not early '63 ( I believe these are all from 63, there is a difference in the part that is riveted in the front. A straight piece is early and the part shaped like a T is mid to late)

Are these any other identification marks that can ID these further??

Thanks

Can you post a few pictures. My answers/opinions are in your quote.

Martin, It's just the opposite, the metal rivets are used in 63 and (I believe) 64 and 65. There are quite a few differences between the 63-67 top shields.

Hi Martin,
There is a great article in Vol 12 # 4 of the NCRS Restorer on Radio Ignition Shielding for the 1963-67 327 engine cars by John Amgwert. It shows the 5 different top shieldling designs as well as all of the lower shielding changes. It is a 12 page article. We have used the article with examples original shielding for judging sessions at MAC Chapter meets.

63-3 metal rivets. '64- 2 metal rivets, '65-67 2 plastic rivets. Differences in the grounding piece in the front that hits the aircleaner between '65 and 66-7 are some of the things to look at.

65 was a change-over year from metal to plastic rivets so a 65 could have either ones OR one of each which is how mine left the factory.

Martin,
Make the effort to get the item Page Campbell listed. The details and changes are far beyond what can be explained here. Showing some pictures will allow members to id them, but its a corvette and nothing is definite.

Thanks Vinnie - that's had a major update from the earlier Restorer (have V 31.4)

Re: Mid-year Ignition Top Shields

The info. in the above article regarding top shield front contact clips on 65's is incorrect. There are many examples in Noland's Resto. Guide Vol. 2 that show 65's using the earlier (late 63 - 64) clip. My 65 has the earlier clip as well.

Vinnie,

Thanks for posting this article! Do you (or does anyone else) know if there was a different configuration for the ignition shield for the C2 BB (L71)? It had the triangular air filter so I'm wondering if there was a different configuration for that. The article is specific to the small block 327's??

Thanks Vinnie,

Take care,

Re: Mid-year Ignition Top Shields

Its been a long time since I thought about it, but I remember three types of BB shields. The 65 had the house cut out for the point adjustment door, the early 66 had a long front skirt, and the later 66 with aluminum intakes had the short skirt. Some time later 66-67 all had the short skirts.
