Thinking about putting an fj60 rear axle in the Piggers to match the front, more for making the tires the same width, not so worried about having all 4 disk brakes although that will be nice. From what I understand all 60's had 3.70 gearing (63 was 4.10?) which I like, but I read somewhere that in '85 Toyota changed bolt patterns for the driveline? Can anyone confirm/deny this? I'm running a '90 5 speed, so I don't want to match the original fj55 transmission bolt pattern...
