A departed good friend once said they should just make one set of instructions for ALL aftermarket parts.
1. Take off the old sh-t
2. Bolt on the new sh-it
3. Turn the key and go laugh2

Over the last 50 or so years I have found 4 exceptions that come to mind

1. Schumacher conversion mounts
2. Trim parts
3. RMS suspension
4. Legendary interiors
