Hi everyone,
I own a 1969 Datsun 1600 (510). I'm wanting to carry out a steering rack conversion to it. This would be making use of and engineered setup brought in from UK. The setup makes use of new Lower control arms(LCA) Spacer material for LCA positioning Mk2 Escort steering rack New steering arms New tie rods New bushings throughout then a new steering column kit that consist of 1x upper universal joint which is welded to the new chromoly splined column shaft 1x lower universal joint splined to match ford rack New double sealed ball bearing
Nylon bearing support bushing
Aluminum outer housing clamp
Can anyone tell me if this needs to be run past any engineering assessment and then what cert requirements it would require. Specifically I'm thinking there will be some sort of bump steer requirement?
I've attached some pictures to help
any help would be appreciated before I fork out the cash for this and find no one is willing to cert it.
thanks.

Gidday, Sinfull A brief look over the list showed one item that caused immediate concern, the "1 x upper universal joint which is welded to the new chromoly splined column shaft" our standards do not allow ANY welding to steering components, except for OE welds. Unless a new part/parts is made that eliminates any welds, then you would not be able to use this kit in it's entirety. If you think that is a problem you can resolve, then the next step would be to prove the suspension pivot points are identical between OE and aftermarket. This would require the OE and aftermarket crossmember and lower control arms presented to your certifier to take accurate measurements and confirm the pivot points are identical between OE and AM. If they are not identical then it would require TAC approval for a custom IFS. This info-sheet explain that process. lvvta.org.nz/documents/infosheets/LVVTA_Info_01-2016_LVV_Custom_Independent_Front_and_Rear_Suspension_Approval_Application_Guide.pdf
The rest of the kit components would also need a thorough assessment by your certifier to ensure compliance. Unfortunately the only way to assess this is to present the physical components to your certifier. Cheers |

thanks for the response Chris. its a big risk purchasing the kit only to find it unusable. all up I'm looking close to 2.5k to purchase it. Ouch but in the long run worth it.
I will start the process at least with the TAC side of things as speaking with the manufacturer they already said that the pivot points are changed to reduce the bump steer issues when lowering these old Datsuns.
thanks again.
Matt

Matt No problems, feel free to ask more questions here or email chris@lvvta.org.nz if you prefer. |

Ive decided to at least go down the TAC route to begin with. Not having done this Is there too much info I can send them. reason for the question is the designers of this setup have a heap of design info on their website that I can imagine would be helpful for the TAC guys to make a fully informed decision. To be honest it looks very very well done.

To be honest it looks very very well done. If you fill in the 4B form and also send through relevant supporting evidence (for the items that you are seeking approval) that should be sufficient. Also sending through supporting information about other modifications you are carrying out and are not requiring TAC approval is not necessary. |
