Looking for one of these-located on passenger side of 5.7 350 Formula. I am replacing plug wires and this one was barely hanging on-it is cracked. If anyone has one or can point me in the direction of purchasing new, would be greatly appreciated. Couldn't find anything on the internet. Thanks in advance.

Update: Went wandering around the local pick it yard in the GM section this weekend. The majority of the cars in there are 6 cylinders, but did locate this tiny part.
Found it on a 95 4th gen f body with an LT1.
