Hello all, I've had a good look through the forum but haven't quite found my answers.
How is the 60% rule interpreted: Do I need to include a minimum of 60% of the original chassis/chassis design in the chassis build Or, Does the original chassis/chassis design need to make up atleast 60% of the finished chassis.
Also cant answer myself in my hobbie car manual.
Reason being is I'm building a 50s chev thriftmaster pickup, converting from solid front axle to a hilux front end, c-notching the rear and adding additional bracing and strength for an engine upgrade. Just worried the 60% will come up really quickly. Or is it possible I can graft 60% of the chevy chassis ontop of the hilux chassis? The running boards hang a fair bit lower than the original chassis so wouldnt alter the aesthetics.
Sorry for the long winded post, just wanting to problem solve as much as possible before I go annoy a certifier.
(ii) retains, from the originating mass-produced vehicle, 60% or more of the original or authentically-repaired body, (including panels, but not including external sub-panels), and 60% of the original or authentically-repaired chassis rails (or in the case of a unitary-constructed vehicle 60% of the floor-pan);
Is what I can find but is still a little vague. - I must include 60% or more of the original chassis - complete finished product must be a minimum of 60% of original chassis
There are multiple variations suggested in your enquiry above but from the information you have provided and providing that the vehicle meets all requirements for entry compliance. (assuming the '50 has not already entered the national vehicle fleet) it would be likely that a '50 Chev Pickup body on an original '50 chassis with a Hilux front clip and a c-notch would be regarded as a Mod Prod, adding bracing and strength to the chassis would be additional and not dilute the chassis percentage.
However if you were to mount the '50 body on a largely complete Hilux chassis and add parts or sections of the '50 chassis then it would be considered a Scratch Built.
If you are at all in doubt then I would recommend you get in touch with a certifier to complete an F010 Form (Application for Statement of Authenticity) and include photos and sketches of your plan for LVVTA to make an accurate assessment of the classification and let you know where it lies. In fact you should stay in touch with a certifier throughout your build so when it comes time for certification then your certifier is familiar with the vehicle and how it was constructed.
Hi Budfid, It's the total material/area of the chassis, not just the wheel base.
If your vehicle is that close to the line, then we suggest having a good read of the document mentioned above, and complete the F010 Statement of Application Form with the required info. Our Technical Working Group (which includes members of our Tech Team along with Technical staff from NZTA) can assess the info and photographs/supplied drawings to come up with an outcome.
Hope that helps.
