This small collection is about 10 years worth of collecting. These heart shields are very difficult to remove from the exhaust manifolds without destroying them. therefore they are somewhat rare. This collection came from many different cars and engines and it is up to you to determine if they are what you need or want. I do not recall which ones apply to which cars and engines. Sorry I will not b read up the collection. You get them all for one low price of $75 plus $16 for shipping.
