1964 Left Side Ignition Shielding ?

[M W.]

Can anyone tell me if a truly original left side lower ignition shield should be stainless? If so should a magnet stick to the original? Dumb question I know but I need a definite answer.

Thanks,
Craig

Yes, they are stainless; and yes, they should be ferromagnetic.

Craig;

Believe 63's same or similar (not R.H. though). I have seen nothing but S.S.. Drawings on some of the pieces call for either or, but I've never seen chrome L.H.'s.

Craig.....Yes I believe Stu is right. Here's a photo of original shields on our 63, and a few more below on the bench. I believe 64 was the same.

According to the prints in Noland's book for both: Left front 3819753, Left rear 3819755.
"Material: RISI type 430 stainless steel, 16% to 18% chromium. .031-.039 thick.

p.s. I'll do the magnet test later when I get the hood open.

FYI We inspected many original samples before making the reproductions.
some were magnetic and some were not.

the repro we have are stainless steel, but not magnetic.

Re: 1964 Left Side Ignition Shielding ?

The GM parts drawing presented in another thread that documents the basic material used seems to be an effective argument countering the small sample error potential associated with inspecting 'known original' parts...

I know you can't always rely on the drawing system to be 100% correct (new vendors come on stream, temporary deviations are sometimes authorized, changes over time happen and may not be documented), but doesn't it seem that source drawings along with known original part sample analysis is the way to go before committing to certain formula for a reproduction part?

Sure is nice to see Richard Cohen, long time member, adding his insights.
