I would like to rebuild or build a new one from plans and parts but need to find a substitute for the original canopy. Tower/G.P. wants $13.00 for one and another 13.00 for shipping last time I called. Are there any substitutes available?

I think $13 is a pretty good deal ..You might be able to make one out of a pop bottle or go with the open canopy look..You could also build a wooden one..
