Exhaust Preheat Sheild Tech
 

I have found three different exhaust preheater shield designs in my parts stash.

The top two sheilds appear identical except for the cutout on the bottom left edge.

Can anyone ID the correct application for each part pictured here?

Thanks in advance, John

Bottom I believe is from a 68-69 Firebird, Top left is identical to my 68 GTO, top right not really sure but appears to be something that goes on same side as dipstick possibly

This was exactly my thought when I saw it, but I will try to remember to check my 68 Firebird's shroud in the next couple of days to be sure (non-Ram Air). Posting here and getting e-mails for new posts will help me remember.........................

Yes, the bottom one is the same as the one on my 1968 Firebird standard 400 automatic.

The one on top on the left is the same as the shroud from a 1969 LeMans 350 automatic--I have one.

You may be able to use a MPC to match the shroud part numbers for these 2 car models and see what other cars/engines used the same shroud. The LeMans 350 shroud may have been the same for a standard GTO engine, but I'm not sure.
