Looking for sump guard, bolt on cage/harness bar

Hi all

Recently gotten my MG ZR going and noticed it scrapes the roads from time to time (they're pretty bad here) already punctured a sump, currently got the spare on it, hunted about but couldn't find anything

Same as a harness bar, bolt on cage isn't as difficult it's just i have the 5 door hatch and it won't pass vehicle inspections unless the back seats are in and I've no clue if any of the cages will fit without removing the seats or dash

Thanks
