What do K-Line O-27 Gauge and "O" Gauge Super "K" Switch Conversion kits look like?

I saw them listed as K-570 (O-27 Gauge) and K-670 (“O” Gauge) in some K-Line catalogs, but no pictures were included.

Did they consist of clip-on Super “K” ties, or was a certain amount of disassembly/assembly required?

Does anyone have pics of the kits and/or the instruction sheets that came with them?
