Body and Chassis Mod Plates (LH), Brisbane
Changing a roof, wheelbase or body style? These need an LH mod plate. Autocert checks the plan and certifies the finished work. We don’t certify street rods (LH9, LH10).

What we certify
- Roof conversions, such as convertibles and chop tops (LH1, LH2)
- Wheelbase changes (LH3, LH4)
- New bodies on a chassis (LH5, LH6)
- Body variant conversions, such as ute to wagon (LH7)
- Campervans and motorhomes (LH11)
Typical jobs
- Convertible conversions
- Ute and wagon conversions
- Wheelbase stretches
- Fibreglass bodies and tilt fronts
No plate needed
Bolt-on panels, bonnet scoops, and mudguards that meet the rules.
Before you book
What to send
- Rego and VIN
- What’s changing: wheelbase, roof or body
- Photos or drawings of the plan
Should I talk to you before cutting?
Yes. Body and chassis changes are much easier to certify when we see the plan first.
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.
