Hello Roger,
Many thanks for this. Your picture confirms what I thought. On my car the lower shock mounts below the axle leaf string are still there but not used. Instead the shocks (which look quite new) are attached to new mounts located on the top of the leaf spring (ie. on the mounting sandwiched between the leaf spring and the axle). I suspect someone couldn't find the right length of shocks and improvised ....or is this a standard work around for currently available shocks. Crawled underneath to take the attached photo to illustrate what I mean.
I discovered after some testing what everyone else I guess knows. The left hand under dash toggle switch works the footwell lights and the right hand one works the radio ariel.
A closer look at the manuals does indicate a Torx Star type drain plug on the fuel tanks so it must be an original one.
Also attached is a photo of the dual circuit booster, can anyone identify it as this would be helpful in the future if I need spares.
Kind regards,
