Good Afternoon John;
Was very impressed with your website.
I am half way through restoring a 1969 Series 2A Landrover… and im up to the breaks. To convert to disk breaks I have replaced both front and rear complete hub to hub diff housings and put in ones out of a 1988 Ranger Rover. To do this I had to cut off all the old coil spring stuff, and weld on leaf spring mounting points. I got someone to professionally weld it and have a certificate of strength. The diffs are a slightly higer ratio, but still have the same mounting points and type as the old diffs so no changes to the drive shafts required. They are also slightly wider than the older diffs. The front one is also slightly offset (about an inch) to the left (ie the left wheel is a slightly different distance away from the center of the car compared to the right wheel). Do you think there would be any issues with certing all of that?
My plan now is to self install a new break booster and master cylinder, and get new lines run professionally. What are the certifcation issues regarding running of the new lines any hiccups I should know about? There are two inputs on each of the front callipers so plan to run just one fixed line to each side with a T junction at the chassy to accommodate this.
Hi Andrew
This sounds like quite a complex conversion. What you have done sounds fine, and I can’t see any problem so far. Fitting a new master cylinder and booster seems straight forward, but
1 Make sure the they are of a suitable size- e.g. similar to what the Range Rover would have had.
2 Look into how the dual circuit system was set up on the Range Rover, and try to copy this. Some vehicles had two seperate circuits to both front brakes so that if one circuit failed, you still had two front and one rear brakes. If this is how the Range Rover Brakes were meant to be, better to keep them that way.
3 Front to rear balance- I don’t think that there would be a proportioning valve on either vehicle, but check anyway. There MIGHT be a load proportioning valve on the Range Rover, this would be good to have if you can.
Hope this helps

hi, was wondering if anyone knows what the nz stardards are for building a motorbike frame from scratch? i’m a qualified welder so that shouldn’t be an issue just needto know if there are any guidelines i need to follow. Thanks
I suggest you give Alex Gee a call on 027 2647282, or email him on geeam@ihug.co.nz
Hey, a query on engine swaps. If my car was cat-equipped when it left the factory, is a cat required for certification if the engine that’s being swapped in was produced cat-less in the UK in 1989? If not, is the engine code enough to prove this, or will I need the rego plate of the donor car? Thanks.
The LVV Rules say- Cat required if original car and the new engine had a cat. If one of them didn’t, you don’t need to have a Cat. Some NZ new japanese cars did NOT have a Cat, whereas same model used import DID. What car? What Engine?
Hi, I want to make a carbon fiber hardtop with some sort of poly carbonate window for my Mazda MX-5, am I going to run into any certification issues.
Hi Thomas- I don’t think there is any need to Certify this- the only issue I can think of is making sure there is a label on a polycarbonate window for the benefit of the WOF inspector. Most suppliers will be able to cut the piece, and fit a label. Cheers John
Hi, in the process of changing my power steering pump, can I use aeroquip power steering braided hoses, they are a ptfe hose listed only for power steering, however they are not a crimp design. I see Brake hoses are not permitted in the threaded nut design, thanks for your time, Steve.
I do not believe that there is any specific rule for PS hoses, except ‘fit for purpose’. The hose you mention would seem to meet that requirement I think

Hi, I’ve just put some lowering springs in my prelude which brought some structural components below the 100mm threshold. I was wanting to know if there is anything I can do to raise it up approximately 20mm without requiring certing. I have read the lvvt threshold document which looks like it rules out spring spacers and remachining custom tophats, it that correct? I was also looking into making some shock spacers to sit between the top of the shock and the body of the car, would that require certifying? (similar to what is described on this site: http://www.toyota-4runner.org/5th-gen-t4rs/86370-sp8ball%92s-mod-thread-stealing-other-poster%92s-ideas-since-mid-2010-a-6.html)
Thanks,
Max.
Hi Max
My suggestion would be to get the springs pulled out a little bit to get 100mm clearance.
Regards
John
Thanks for the quick reply John. I would rather make a shock spacer for this as I have the resources to make a nice job of it and by doing it that way I can tune it to get the right amount of lift; I worry that resetting the spring might be a bit hit and miss. Are you saying that using a shock spacer would need certifying?
Thanks again,
Max
Hi Max
I wouldn’t have thought a spacer would need Certification
The problem now is that LVVTA make all the decisions, and could disagree with me
Note that I am no longer a LVV Certifier
Your call, sorry

Hi I own a Nissan Terrano R50. I have been given a dickie seat originally fitted in a Toyota Camry. Is it possible to fit this seat to my truck? Thanks
If this is a seat made by “RETRO” you need to talk to them. Otherwise it would need to be LVV Certified, and that could be a problem for you.

John
Hi John, maybe a little outside the scope but thought you’d be the man to ask, I have a truck with a modification declaration for a Chevy 350ci&th350, however this has been replaced with a 253 & trimatic. Will my vehicle require certification as a result? Thanks
I believe that “Declarations” expired years ago, and were all replaced with Low Volume Vehicle Certifications. As far as I know, you will have to go through another Low Volume Vehicle Certification for this vehicle.
Note that I am no longer a Low Volume Vehicle Certifier.

Yes, this is a good post without any doubt. You are actually doing a great job. I am inspired from you. So keep it up!
Thank you Frank- your comment is appreciated.
Hello John, I have a sidecar attached to a motorcycle, the sidecar is a velorex, The frame is tubular with a fibreglass body. I am in a wheelchair and need some funding from ACC to enable me to return to motorcycle. I need to cut the back of the fibreglass body to enable a wheelchair access. ACC require these modifications to be certified in order to get me financial support. Can you give me some advice on this project and circumstance?
Hi Nino
The legislation around Motorcycles and sidecars is vague to non-existent
