[No clipping for scenery?]

Is there any mods for removing clipping with scenery? Either completely, or just allowing you to build on the same block as a ride or something. I find myself having to build outside walls sometimes, which you know makes those weird looking walls.

 

That, or has anyone made welders / any good scenery item for hiding the exposed corners?

[RCT1 Music for title screen]

Does anyone have the file for it? I don't have the first game but I have the scenarios from a pack on another forum and I just wanted to set everything up in RCT1 style.
