I need help fixing a melted Rear Brake Master Cylinder Reservoir on my 426. I have a white brothers exhaust and I guess it was to close and touched the reservoir. It is melted pretty bad but the cap appears to be fine. The problem is no dealer carries them(in stock) and I need one by Saturday for a Harescramble. Does anyone know of a another year, make, or model that may fit. It does not appear to be leaking to bad. Worst case, If i had to silicone around the cap would that work to keep it form leaking.
