did my best to show what it looks like afterwards. I also inverted a peice of trim ontop of the lower retaining wall to give the track a nice thick, level, solid platform but you have to use 1/8th inch for that so the trim fits onto it as well. I know its kinda thin for the bottom peice but I have not broke any yet ( knock on wood )

also my 30 breeders had trim to thick on them So I had to do it slightly differnt and place extra track on the side so there was a good fit and place it all inside the trim
