OK. Sorry. Just checking. The original post is about an NC8 which was Ninco's replacement for the NC1. It should be a drop in exchange.
The NC1 is standard S-can format.

The only difference in the NC8 is the lack of rounding on the can corner.

The NC5 mentioned directly above is indeed the long can.

Many of the Ninco chassis that were designed for the NC1 motor have a mounting bracket that can be removed and the long can dropped straight in.
