Back in the mid-70's when I was working in REME Workshops, we had unit's vehicles in to fit these kits, whilst they were undergoing NI training at a nearby base. The vehicles were in the main, Land Rovers, both 88" and 109" Ser 2a plus Lightweights, ambulances and Bedford MK lorries. Some of the Land Rovers already had 2 or 3 sets of bolt holes in the body where kits had been fitted for previous NI tours of duty. When the Series 3 came into service, we did some of these, but there was then a policy change where vehicles were fitted with the kits and left in NI, rather than units using there own vehicles. It was a damned awful job as sometimes we had new kits that often had to be trimmed to fit and the fibre glass used to get in your clothes and make your hands itch. Oh and we had to fit Aeon rubbers to the top of the front springs as well.
