There is one possible problem with your mining effort. The more common
caliper used on 86-91 is Girling brand. It uses it's own carriers. There
were some ATE calipers also fitted around 89 but these use a different
carrier mated to them. Since the guide pins are what attach the caliper
to the carrier there might be a different pin used depending on which
brand is involved. More digging is needed.
