YES!
1) Remove rear bench
2) Fold seat backs down
3) Remove passenger seat headrest and recline the seat as far back as it can go
4) Feed bumpers through rear seat cavity, fit sideskirts through passenger door, throw door panels and boot spoiler in the boot
5) Lay rear bench on top of your recently aquired bodykit!
6) Have a celebratory cup of tea
You might want to lay a protective sheet over your passenger seat.
The car pictured is a Cavalier Turbo which has a raised boot floor (IRS) so fitting this lot into any rear beam edition Cavalier saloon should be even easier.
This How2 is dedicated to McFall1984 and PlanetC! Thanks to State for help lifting the bumpers in
