I bought a Sami that cranks and runs like a top but it needs a lot of little things. I want to use it for an every day driver. The windows roll up and down but the drivers window just rattles around. It needs all the gaskets and such. The cranks work but have no handles and the splines are worn from cranking them up with vise grips. All the glass is good so I was wondering if there are any rebuild kits for the windows. Also it needs a muffler so are they available or is there a good substitute.
