Starter Shims Or Starter Backplate

Can anyone tell me if the 1992 302 had either starter shims or a starter backplate?
I just bought the car and noticed that the starter pinion gear takes a second or two to release from the flywheel.
Since then I've replaced the starter and the flywheel but I'm still experiencing the same issue
It's a 5 speed manual all original bone stock 5.0
 
There is a plate that gets sandwiched between the block and the bell housing.
The starter uses no shims.
Either the starter is getting worn out or there may be an issue with the ring gear on the flywheel.
I have had vehicles that had no plate between the engine and trans and some with and the starter works ok either way.
My current Mustang has no plate between the block and trans.
I am running a newer (94/95) mini starter and not the large original style typically used on a late 80's Foxbody.
 
Just FYI. If its the newer style starter it could be wired wrong. The big wire goes to the same side as the battery positive on the solenoid. The smaller wire goes to the other side of the solenoid.
 
^ Right. It centers the starter. The end of the starter has a machined lip that slides snug into the hole of the plate.

It also supports the starter every time you start the car. Otherwise all the torque generated when starting is transfered to the two starter bolts in an aluminum belhousing. The block plate (or index plate) spreads the load of starting torque. Over time the hole in the plate can oblong and cause issues.
