Hi Paul. I've found that "UHU" clear glue is ok to fix clear celluloid, though you have to be careful as it can be very 'stringy'. The 'Pound Shops' are my source for this, as model shops and craft stores charge daft prices for it! I have a few of the long self-tapping body to chassis fixing screws if you're still short, as I completely remove the plastic 'pillars' from the roof and rely on the clips at each end as the pillars are not very pretty and stand out if (like me) you fit passengers and internal lighting. My project is still ongoing as I'm partway through respraying the 3 bodies of my units, and until that's finished, I can't do the internal lighting install or the connecting plugs/sockets between coaches. I've not yet decided whether to replace the glazing with celluloid yet, no point in my buying the 'SEF' glazing as my rear DMB is the one converted to the 'correct' spec using the "Silver Fox" kit, so the 'SEF' replacement glazing will not be correct for that coach. I have no idea what seating colours were used, or what colour the partitions were either, anyone help there? My three chassis have been completely rewheeled and replacement motor bogie fitted, DCC converted and run nicely as a 'train', just waiting in the queue for 'further progress'! Keith.
