Year actually matters in the general appearance of the blades arm. This link has a reasonably good snapshot of through '94 then the '95+. Parking can be tweaked a bit more than displayed in the thread 'if' parts are in very good condition. The same car was used to display both and I'd guess the transmissions, links and sockets were worn and not 'tweaked' for prime park.
**parts = transmissions, links and sockets to crank arm.

This would be maybe 'ideal' for a '95
