Aftermarket Butt Bar

Hello I recently bought a used sliding table saw (Laguna A175014) and it is missing some major features, one that I would like to add. I would like to retrofit an adjustable butt bar onto the wagon. I'm am not real familiar with these machines this is only the second one I have ever used. My plan was to try to find some t-track/extruded aluminum channel and bolt it onto the wagon under the round bar that the outrigger/sidetable attaches to, and then have a bolt in the t-track and then have some kind of large bolt as the butt bar. Here is a picture if the wagon profile. I am open to any suggestions.
