.035 on the plugs.
And yes the reproduction factory manual is what I got. An original would be better if you can find one. The illustrations in the repo ain't that good, but it gets the job done.
I think this is a factory original manual. Worth the $40
EDIT: NO ITS JUST THE BODY MANUAL, Won't have the drivetrain stuff in it.
