TR6 Rear Shock Oil

[Mark Stahlke <mstahlke@denver.infi.net>]

Hi,
   My 71 TR6 is getting a little "springy" in the rear. It looks like the
shocks may have been leaking a little. Does anyone know how to change the oil
in the rear lever arm shocks on a TR6?
How do you drain the oil?
How much of what kind of oil do you put in?

Thanks,
Mark
