Mechanically speaking, the TracKick and Samurai distributor are, physically, very similar.
Follow especially what wildgoody's and chet's post say --
Use silicone grease to hold the large o-ring in place on the head so you don't crush it and start another leak.
Before disassembling the distributor, carefully mark the positon of the distributor adjustment bolt AND where the rotor is pointing relative to the distributor case. That way, when you put it all back together, you will be exactly where you were - timing wise- when you started if you re-match all the marks.  You may need to remove and rotate the rotor a few times to get it dead-on but at least you can eventually get it to match the original position...
Take it from a guy who has NOT marked then disassembled -- it ain't no fun spending hours trying to get the timing back.ÂÂ

Thanks for those kind words, da_tub!
