By jove I think we have it.
Mates bike has Manitou SX LT forks c1999 & had formula brakes with 185mm front disc & 140mm rear disc. Front & rear calipers are exactly the same (unlike XTR m965), the IS rear mount with no adaptor is for 140mm disc, the front had a post mount adaptor (silver one in photo) for 185mm disc.
Odly enough I have the red adaptor that I bought for my XTR's but it wouldn't fit, does seem to fit the formula brakes though
I'll pm you as I don't want any of this stuff.
