The Previous Owner (PO) went old school and did not replace the stock coolant overflow reservoir routing the overflow line to the ground. The original bracket to reinstall an OEM tank was missing as the tank would have been located on the passenger side of the engine compartment which is now filled with the pre-1981 air filter canister. After a bit of searching and research I went with this little stainless steel radiator fluid reservoir from Mr Gasket. Model#9135. Perfect fit for the mounting bracket on the driver side of the radiator.
