You really need to remove the timing belt, but if you are not comfortable doing that, it is possible (but difficult, time consuming, and rather annoying) to recover static timing by another method.

Your first limitation will be fitting the distributor under the manifold.  There is not a lot of room under there so do what you can to fit it such that you can rotate the distributor body as much as possible.  Next you have to identify which terminal on the distributor cap best lines up with the rotor (i.e. #1 plug wire).

Once you attach the plug wires to the cap (1-3-4-2), oh, and BTW you WILL install them backward at least once!  then you can take a reading to see just how far off you are.

I suggest you get another set of cheap plugs, install them to the wires and lay them on the intake manifold where you can see them.  Label 1-4.  When you rotate the engine by hand you can see (and hear) each plug fire.  Note the timing when 1 & 3 fire, 2 & 4 will be 180^ out of rotation (that is IF you installed the plugs to the rotor correctly!).

Now comes the fun have to rotate the distributor and possibly reset the plug wires on the cap in order to get static timing for  1 & 3 to approximately 10^ BTDC.  This will be a very frustrating and time consuming process as you iterate to a solution.  Each time you move the distributor, you have to rotate the engine several times to check and re-check the timing, your knuckles will NOT be happy.

At the end of the day, there may simply not be enough room under the manifold to rotate the distributor enough to make it all line-up.  Then you're back to removing the timing belt.

Again, take your time and you'll do just fine.
