HI Paul. I'm assuming here that you're using a series DC motor because I don't recall that GE made any EV1 controllers for separately-excited motors. I may be wrong about that, however. But if your motor is series-field DC, and the GE EV1 is indeed not among the living, and time is more important than the budget, the quick fix would be to replace the EV1 with a modern controller. I guess you could say that Curtis is a more or less "standard" choice here. They've been making road EV controllers for for many years. Their former incarnation, PMC, built the DCC-96 bipolar transistor controller used in the Bradley GT EVs in the late 1970s. Something like a Curtis 1238E-6521 (rated for 48-80v systems) should be plenty to get your car rolling, assuming you have a 60v battery, which your message suggested. There are other reputable brands, such as Zilla and Alltrax, but 60v seems to be kind of in a "no man's land" these days. Kelley controllers are cheap, but I've seen mixed reviews of them. Maybe others here will have further controller suggestions. Please let us know how it goes. We're pulling for you and your uncle!
