I had ordered some bearing for my 5mge rebuild. I ordered the kit for the 84-85 engine. The kit I recieved had a large #1 bearing, while I needed the thinner one.... I have a 85 Supra, so thats sort of weird. Is there a place where I could buy only one bearing? I was also wondering, is there a serial number somewhere on the engine to see if I have a 85 engine with more power, or the one prior to that with less?
