From what I have found searching, my 66 VIP with a (318) has a TRW/Thomspson P/S pump. It has a leak/drip on the bottom of the housing. I purchased a seal kit from Ad.... which according to them, states it's for a Chrysler pump for a 66. The seal or large O Ring seams a bit to big. Doesn't sit in the groove tight. Does anyone know of somebody who carries the correct seal? I've checked other local parts stores and on line. Can't seem to find a seal kit particular to a TRW/Thompson. Any input would be helpful. Thanks
