JimNNN, you really should to start a new thread. When mixing different cars and engines, it gets confusing. You mention a T-bird distributor but there are different engines and distributors in T-bird cars over the years of production. We don't know what year or what engine you have. All cars with built with vacuum controlled spark timing benefit from a working system whether the beaker is a set of beaker points or an electronic form of trigger.
