89' Ford F-150.
Looking at purchasing a 1989 F-150. When I tookk it for a spin, I noticed oil dripping from between Transmission Case and Motor. My brother and I believe it may be a Rear Seal Leak. The guy is asking 1K. If we are right about the leak,is this a worthwhile investment or can I fix the problem for a few hundred? Other than that, it is a really clean truck, no rust, good shape for going on 20 years old. Thanks in advance.
