Is there such a thing as a uni track to ez track conversion piece? I know theres uni track to tomix convertor but my collection came with a ton of ez track Id like to put to use. Visually is hard to tell apart but the connector is different.
No there is not, but it also is not needed. Just cut off the end of the E-Z Track that is designed to lock into the next piece and use regular rail joiners to connect them. You may want to shim the end of the Unitrack a little because it's road bed profile is shorter than the E-Z Track, but I've used them together without shiming. You will end up with a little "hole" in the Unitrack where the Unijoiner was. If that bothers you you can remove the metal from a Unijoiner, cut it in half, and insert it in the Unitrack to fill the hole.
You can make your own! Take one piece of Unitrack, and one piece of EZ track. Slide the rails off and cut about an inch or so (same length from both) of roadbed off the end of each piece. Slide the rails back onto the remaining roadbed; and slide the "other" end onto the remaining rail. Voila! You now have two pieces of track with EZ Track at one end; Unitrack at the other.
