I am finding that certain parts are hard to near impossible to find while others are easy because of companies like Classic Industries. Because of that I wanted to ask everyone what parts you had trouble finding when restoring your car. For example, my RR originally had a front bench seat and I have been unable to find a frame. I have a few leads now but it took time to find them. So what other parts are tough to find or are typically not remade by companies like Classic? This will help give me some guidance on what to spend time looking for.
