Are you talking 2" lift as in body lift or do you mean changing the shocks & springs?????
A 2" body lift is a lot of work,
You'll have to take off and fit spacers to all the body mounts.
The mounts will probably be well rusted and may well snap when grunt is applied.
If you're up-grading the springs and shocks to 2" longer items then this can be done quite easy,
the best way of doing it is with spring compressors,
if you dont have these a good jack will do the job,
the brake pipes do not really need changing but it is peace of mind.
Good luck,
Ron.
