[Mgs] Raising motor to change mounts

[Paul Hunt]

Not sure I understand this.  AFAIK the 77 and later mounts are to the same 
design (albeit slightly softer) than the V8 and the chassis brackets are 
identical.  My V8 mounts have two holes in 'ears' on the side of the mount 
that goes towards the engine, for bolts to attach it to the engine, plus the 
off-set stud that goes through the chassis bracket.  Incidentally the mount 
must be orientated such that the stud is in the lower of the two possible 
positions.  The chassis bracket has a slot cut in it rather than a circular 
hole, and this serves two purposes.  Normally one would attach the mounts to 
the engine and lower it into position.  The studs are at an angle and so the 
slots allow them to pass through the chassis mount (the engine being lowered 
vertically), which they wouldn't if they were only plain holes.  It also 
allows for dimensional differences between the chassis rails by allowing the 
mounts to sit higher up or lower down as appropriate.  Sometimes shims were 
added if the engine sat too low, as the exhaust on the V8 can hit the 
steering shaft and the inner wing.  The stud has a large flat square washer 
plus a split washer and a nut to secure it, none of these 'lift out' when 
the mount is lifted up, they have to be completely removed.

One of my standard spanners (inherited from my father) fits in the space to 
tighten/undo this nut.  It is called a 'slim jim' or something similar, but 
doesn't seem to be that much slimmer than my modern spanners.
