2.0L engine sheet metal

I've installed nearly everything on my 914 that goes on it. As many of you know I put a 2.0L out of a 1974 into my 1975 car (prev. a 1.8L). I have a couple of pieces of sheet metal that attach to the heat exchangers (I think). I think these pieces only go on a '75 and '76. If you follow the link below it is the piece 3 and 4. The link below refers to the '73 and '74.

What exactly do the pieces do? I've had type 1 motors in the past and they didn't have these 'extra' pieces of cooling tin. I'm sure they are there for a reason but I'm wondering if I can drive it around like it is for a while.

Anyone have these for sale?

Thanks all and God Bless America,

They are "warm air guides" that direct warm air towards the rear of the car. I also think they protect the pushrod tubes from crap flying up and hitting them. They are a different size and shape for the 73-74 cars than the 75-76 cars. This is due to the different exhaust systems. I hope you are putting the 74 exhaust on your 75 car. It gets you a few more hp as it is less restrictive. Yes, you can drive around without them lots of cars have them lost them over the years.

Thanks for the info guys. I've got '74 2.0l heat exchangers with Borla exhaust.
