Seat, Seatbelt and Roll Cage Mod Plates (LK), Brisbane
Added or removed seats, fitted new seatbelts, child seat anchors or a roll cage? Changes like these usually need an LK mod plate. Autocert inspects and certifies the work. Any good mechanical workshop can do the install, and we sign off the finished job.

What we certify
- Adding or removing seats and seatbelts (LK1)
- New or moved seat and seatbelt anchor points (LK2)
- Child restraint anchors, such as anchor bars and posts, in vehicles without factory points (LK6)
- One-off roll bars and roll cages (LK8)
- Fitting approved aftermarket roll bars and cages (LK10)
Typical jobs
- Rear seats added or removed in a van or 4WD
- Bucket seats in a classic
- Child seat anchors in a dual cab
- A roll bar in a ute or soft top
No plate needed
- Fitting the factory seat and seatbelt for your make and model
- Replacing parts with identical original parts
That’s as long as the anchor points, structure and seating capacity don’t change.
Before you book
What to send
- Rego
- Seats or belts added, removed or moved
- Whether child restraint anchors are affected
Do I need a plate to remove a seat?
Yes. Removing seats to reduce seating capacity needs an LK1 plate. Any holes left in the floor must be blanked off, and the removal can’t affect the airbag system.
Need a mod plate?
Send your rego, VIN, photos and a list of changes. We’ll confirm the codes and give you a fixed quote, usually within a business day. Mobile across Greater Brisbane. A travel fee may apply further out.
