Can someone with an original oil pressure gauge in their 69 Z-28 post a picture of the fitting in the rear of the block? I still have the original oil line, which has a female fitting that screws onto the fitting on the back of the block. I bought one of those brass extensions that people sell on eBay, and it is a female fitting. Is there a male/male coupling in between or did someone sell me the wrong part on ebay (shocker!)
P.s. It shows the extension in the assembly manual, but not a very good pic.
