Old hands probably know this already but here is a tip for the less experienced.
Most manufacturers use self tapping screws to fix the body to the chassis, repeated undoing and replacing them can eventually destroy the thread in the plastic because they try to cut a new one each time. Use the following method to avoid damage when reassembling your cars:
Insert screw and turn slowly
anticlockwise until you hear and/or feel a click. It is now lined up with the start point of the original thread and can be tightened safely.
It is also a good idea to replace the stock screws with ones like these
LINK or longer ones like these
LINK. They have a thread-less shoulder at the top which helps achieve good body rock.

Any good tips for anyone who has stripped the threads on their body mounts?
Have read about dripping some glue down the post and insert an oily screw to form the thread. Can only see myself gluing the screw in place!
I love puttering with gears

If you adhere to the process in the first post and start your screws anticlockwise until they seat, (and don't reef them tight) they should last indefinitely. As well, often folks end up using different screws for each body post, so reinserting the same screw into the post will help.
That said, folks do strip body posts so.......you can put some styrene glue into each stripped post, let it dry, and re insert the screw (zero need to oil it).
If the post is really bad, you can find some styrene rod the same diameter as your post hole (evergreen makes tons of various diameters), glue this into the post with styrene glue or plastic weld. let it dry, and drill a new hole.

Thanks all. I have some Hypo Cement glue that should do the trick.
[Need to learn not to over-tighten the screw as well!]

Smear of super glue on a toothpick, insert and rotate.
Do not put too much in!
Split posts can be super glued and secured with shrink wrap tubing.

Thank you.
It's a great help to get guidance that turns a big thing in my head into a little thing if I follow your advice.

This is an old trick that I learnt 25 odd years ago from my old man rebuilding motors, it applies to
every single threaded item in the world.
If you do this every single time, you will extend the life of the screw mount and the threaded item for decades, if you feel any kind of resistance, stop immediately and check the threaded hole for crap or blockages, get your air compressor out and blow the hole out and clean the screw/bolt. If you don't have an air compressor pop down to the local service station to put air in your car tyres and use that to blow out the threaded hole, or get the vacuum cleaner out and suck the crap out, if the misses looks surprised just grin and move along, do the job and pack the vacuum cleaner away, she will winder how you vacuumed the house so bloody quickly, again just grin and move on, curiosity will get the better of her eventually
