1995 and up side valves have smaller porting which allows you to modify them to work on 93/94's.
RH 12005-1183
LH 12005-1182
Here's what I started with, you should be able to use other part numbers
RH 12005-1211 1995/1996
LH 12005-1242 1997
The gear positions are all the same, just the valve port needs to be widened about 2-3mm on top and 1-2mm on the bottom. There is a fraction of a degree of angle to the flat sides of the ports so try to keep that, don't make perpendicular cuts.
I used a marker to mark what I was cutting away, took most out with a cutoff wheel, then used some files to finish taking various measurements from the originals along the way. Took about an hour.
Typical wear, twenty years of steel meshing with aluminum.
