this is the correct version ive watched the tape a million times i study his bass les is crazy so here it is...

intro and main riff
e|----------|
a|----------|
d|5-5-5-5-5-|
g|5-6-6-6-7-|

after doing that a few times he palm mutes 

e|----------------------|
a|----------------------|
d|7-7-7---7-7-7---7-7-7-|
g|7-7-7---7-7-7---7-7-7-| palm muted

then this part is weird he slaps but a different way use your pointer and middle finger...

e|3-2-5-4-3-|
a|3-2-5-4-3-|
d|----------|
g|----------|

then during the solo 

e|----------|
a|----------|
d|7-5-7-5/4-|
g|9-7-9-7/6-|

thats it its  not that tricky you just gotta get the technigue down thats half the fun
