[Healeys] Quick Jack installed on frame.

[Bob Spidell]

IIRC, not sure, that it said that in my 2008 Mustang's shop manual. I 
think that car had the usual iron (steel?) differential housing, but the 
tubes to the rear wheels were steel tubes pressed into the pumpkin. I 
can see how that could be problematic--esp. if the weight of the wheels, 
brakes, etc. was suspended--but I did it several times and the car was 
fine when I traded it in at about 124K miles, with the original clutch 
and brakes. Healey rear axles, I think, are solid iron so probably not 
an issue with them.
