does anyone know what header is used to get the angle up so the left rear tire dosent rub against the stock header on a rc10 gt?
with the shorter rear A arms the tire doesnt have enought clearence to roll when setting level or when weight is on the left rear side

You might try the Associated header for a pull start engine. They make both headers for pull start and not pull start engines. The pull start header is angled up, so it clears the rear tire. I dont have the part number, but would be glad to send you one.......I have a couple.
