The convertable top to my mustang won't go down :( I think it's because I need more hydrolic fluid, but I can't find the place to fill it. It's a 1999 model by the way. if anyone has any information let me know

You need to replace it... there's no, "filling spot". Means the suspension bars are pretty much foooked. It could be that or it could be electrical.... have an electrician run some tests on it before buying the suspension for your top.

No... I filled it like 20 mins ago with hydrolic fluid my cousin who is a mechanic said I need to replace my cylinders

<,< Aren't they lil rods that expand open?... like a shock or a strut? or like the shock from a car's hood that keeps the hood up? When you say cylinders, you mean the rods right? That look like miny shocks?

yeah
