"...Stuff thats crazy rare, you just never see anymore that brings people back to those memories is what I love buying for my car, its a very nostalgic time. Most I guess are lost to history, sitting on the side of Paradise Drag Strip, rotting away."
If you are really serious about buying some of the old stuff, I'd inquire in this thread, AND post ads here, in the classified section.
There are guys here that began racing back in the '50's, & have seen & lived thru it all. Most of 'em know LOTS of other long time racers. Some guys get rid of their old stuff. But, some keep stuff for a long time. Many probably have decent stuff they haven't even thought about, for years.
So, if you ask, you may be able to find exactly what you want. I think Nostalgia racing classes have been quite popular, for quite a while now. So, it may surprise you what you can find out there.
