I have a set of old Cal Custom valve covers, they are sweet. Unluckily, they have a smaller than modern standard hole, 1" diameter. Are there any valve cover grommets that fit 1" and valve cover breathers with PCV hose hookups that will fit this? I can find plenty of 1-1/4" and 1" neck breathers, but I'll need something smaller. Ideally with a smaller than 5/8" hose connector. If you can point me to something like this in polished aluminum, stainless, or chrome I will send you a free gift bag of the stuff I bought that I can't use. Attached is a photo of what I would like, just smaller. (Pictured is a 5/8" PCV hookup and a 1" neck to plug into the valve cover) Thank you for reading!!
