3000 Crank Nut Wrench/Spanner Size

[James Sailer <heliskier@direcway.com>]

Greetings all.. Am in need to pull my timing cover off to replace seals ...
Two questions:

1. What is the proper size of the wrench/spanner to fit the crankshaft nut?
(66 BJ8)
2. Do I have to jack the motor up to remove the crank nut and pull the
pulley/damper to perform this work or is there enough room without raising?
(or how much raising is needed?)

Thanks much for your help...
