The newer kits come with a spacer (holes are small just for bolts) four allen head bolts, and the shift arm.
should be assembled in the following order:
install shift arm in shift tower
put rtv on rubber part of isolator
install spacer on shift tower with original bushings and allen head screws
put rtv on bottom of isolator
install spacer on isolator
put rtv on bottom of blue spacer
install spacer/isolator/shift tower assemble onto top of trans.
you decide if you want to pull up wire harness bracket and put under forward left bolt.
lol
took longer to unhook my Bob V's super shifter than it did too install shifter.
If you have the old kit simply do not use the included bushings and follow the steps listed above.
hope this helps clear up any lingering questions
