I'm looking for a large plastic model of a Cessna 182 RG - My dad used to own several and I want to build one with LED lighting and registry numbers like he had - can't seem to find any non-RC kits -

Any ideas?

I dont think a kit has been made of that. However, there are kits of both the cessna 150 and 172 currently on the market, with a little modification one of those should work.
