first is it normal for a gt's wheels to spin in the same direction when you spin them by hand? or should they spin in opposite directions like my t4?

second should the slipper clutch in the diff be set the same way as my t4....go in all the way then back it out about 1/8 of a turn?

bought this used and it didn't come with a manual so yeah any help would be appreciated.

thanks,
mike
