re: 1720W

Trying to repair AKAI 1720W RTR deck, in which the R/W head has become detached from its housing. It is not obvious how it should be attached and it's not clear from the service manual, kindly available on this site. The vertical plate on the housing has two small holes about 1.5 cm apart, but no tapped holes on the head itself. Surely it wasn't just glued to the vertical plate? There is also a small piece of what looks like insulation which has become detached, with two small holes, also about 1.5cm apart, but it does not look as if it should fit between the head and the vertical plate. If it fits on the other side i.e. head/plate/ insulation, it's not obvious what useful function it would perform.
I have added two photos to help explain. If anyone can advise on how this head should be attached, I would be very appreciative. Everything else seems to be in GWO.
Thanks,
Barry Phillips.
