spitfire u-joints

["Bradley D. Richardson" <brichard@us.oracle.com>]

I need to replace the drive shaft u-joints on my 79 spitfire.  Out of
curiosity, I called two local repair places, and both of them tell me
it's about a 4 hour job.

What am I missing here?  I've done u-joints before, but not on a
spitfire.  Seems to me you take off a few bolts on each end of the drive
shaft, remove it, replace the u-joints, put it back on.  Why are the
'pros' telling me 4 hours.  It make me think there is something much
more going on here.
