Do you by any chance still have a link to the F/A-18C undercarriage MoD / fix please?
You bet. It's on the flightsim.to page for the C model Hornet, one one of the umpteen pages of comments. I created a file for myself for future reference if needed, so I'm going to write it out for you to save you hunting for it.
There's two files you want to edit: flight model.cfg, and systems.cfg. The edits to each, in the [CONTACT_POINTS] and [LIGHTS] sections respectively, are as follows:

That has the F/A-18C model sitting pretty much dead on where it should, instead of all giraffe-like as it comes stock.
Hope that helps,
