my dad had a fiber glass bond 875 hillman imp based car,while driving to wales the engine fell out and was nearly on the rd... no rear cross member it was just bolted into the plastic body
That's too funny! The rear engine mount on Imps was a hanger type mount bolted to the removable rear body panel that was held in place to the body with about 4 fasteners, 2 each side. So, it doesn't surprise me that the engine almost fell out on the ground on the "Plastic Fantastic", as we called the Bond Bug.
Our local Rootes dealership in Erdington, was directly across from the Yenton pub at the corner of Sutton New Road and Chester Road. My Dad being a prototype engineer often had to travel out to the Rootes factory for his employer (The Perfecta) when I was younger.
My recollection of working on Imps, Stilletos and Commer Imp vans, was that they were weird handling little things until their final days when the problems got worked out. Overheating and valve burning was a big issue, so it was good that the engine almost fell out! The "British Corvair" was what we called them, because of the copy cat "styling" and road handling.
I could have the engine out on the ground quite literally in about 15 minutes, following an almost identical routine to the VW Beetles of the day. Off came the rear bumper and back panel to the body with hanger engine mount attached, while the engine and transaxle was supported on a floor jack. Disconnect the electrics, air throttle line, choke and fuel line and a handful of bellhousing fasteners then pull the engine off the transaxle.
I serviced and repaired many Imps in the late '60s to early '70s and also some might remember that Collins TV had a fleet of Commer Imp vans trundling around, some of which I routinely worked on.
Those familiar with working on the Imps will recall the air throttle on the earliest models that was troublesome and replaced with a traditional control. The Stilletto with twin Stombergs was as good as they got, but it was too little, too late with the Minis and Anglias already out there in huge numbers and with way better reliability.
