new type FN for 3rd level on top of old FN type

[Mt. Zion Chins]

I know I saw it here somewhere - where someone actually did this. They had instructions how to do it. I can't find it . I have an old 2 level FN cage that I want to make into a 3 level. However I have looking and looking for the old style on craigslist and others. I can't find it anywhere. So I need to do the new on old thing. Does anyone remember this and were I can find the instructions?

I remember this thread but also can't find it. I believe you have to drill holes into the bottom of the corners to attach it to the old style FN. You'll also have to purchase or make your own connector pieces.

I have an old style FN for sale... but in Nebraska probably not much help, lol.

I did stack a new style CN on the old style FN. Just drilled the extra holes where the pegs need to go on the inside with no problems. We put the new section on top, no additional connectors needed.
