I have been trying to find headers for my 66 GS. I haev found some for 400 but I have the 401. Any suggestions?
You should join the GS Club of America for starters and then enjoy the benefits of having a resource for GS stuff... I believe right now they are running a order for nailhead headers and those will be new! I bought some myself a couple years ago. I wish I had spent a few extra bucks and got the coated ones though...
