When Park was added to the valve body they bored a hole in the casting to allow the manual valve to extend one more position past Reverse, if the VB doesn't have this hole it is a PB casting and won't allow the manual valve into the Park position (your problem getting into Park) The Park problem could also be a misadjusted park cable.

Also, the cable adapter on the PB valve body has a narrow slot ( on right below) that the retaining wire locks into, the column/console cable (on left)has a wider slot that causes lost motion when inserted into a PB valve body.
