Model conversions

[Stinger]

I'm trying to find the document that shows which models can be converted to others and what is required to make that happen.
Anyone have that and can post it here? Thought it was on the Maule Air site, but I can't find it. Thinking it may have been transferred to the other company handling those documents now?
Interested mostly in the MX-7-180A to MX-7-180B conversion. But I want to look at all the available conversions again.

It is on the web site under Support - Mod Kit Index. Just looked it is mod kit #70.
