i had a look for wreckers in the Philippines and found nothing only this ad

http://www.olx.ph/it...=557#e6dc6fc5ff

dont know if they sell parts but maybe worth a try ?

 

i have seen ads for other toranas for sale over there but not very often

Chevrolet 1700 I think is what they were called.

 

I still don't get why but it is certainly interesting what you are trying to do.

 

However, I can't help but think you may be better off importing a left hand drive one.

Just did a bit of reading Maz,

 

where the Racing guy's have steering rack ratio's between 2.6:1 to 3.0:1 lock to lock.

 

The LC torana is 3.25:1 lock to lock, and I checked mine to confirm.

 

Brocky raced with that, so must be OK. 

 

Not sure if this is right, but the pinion should be at the bottom of an installed rack and pinion,

 

just in case you were to opt for a different model rack.

 

 

 

 

 

Edit - Maz, if you can find out what the part# number on the LHD Torana rack is in your search,

 

we might be able to work out what model vehicle she came from.

Only if the rack is installed forward of the crossmember.

And don't forget Dave I, LJ ratio was different.

 

I think it was a little bit faster from full lock to full lock.

That's an interesting thought Craig,

 

So I looked up some specifications,

 

and found the GTR's and XU1's between 3.3:1 and 3.5:1 lock to lock ( my '1969 SL model' is 3.25:1 ):-

p.s. be interesting to hear what other Member ratio's are.

Hi Guys i appreciate  the info very much in trying to help im not very good in the knowledge stakes but having a go 

 

i will ask the uk guys and then Peter in Toronto if they know the part no and ratio for the rack.

 

one fella in UK seems to think that if rack is not in correct i wont be able to fix the bump stop in geometry.i dont know anything in this regard.

 

Ive just thought if its the same length .height etc and mounted in exact pos should work.there shouldnt be much difference really between the viva our hb and the lj

 

Its just the brackets to be fabbed up on kframe thats the difference?  the fella in uk is saying the balljoints? have to be the same distance in my rack as the vivas or i will have geometry issues

Don't know why there are different ratio specs floating around for the LC/LJ 6cyl steering racks as they are all the same  from the 1st LC made in1969 to the last LJ in 1974.

Excellent news Dave,

 

Saves a lot of work finding the right ratio.

HQ-HX ratios changed when they started fitting longer steering arms, but in most cases the same box was used. Might be this?

Here's some pics showing how suspension geometry works with regard to bump steer.





A few mobs make bump steer kits which are basically adjustable tie rod ends.

Never knew about keeping the bump steer components parallel Stephen,

 

great stuff, like button for you,

 

and here is a rough measurement of the LC Torana Rack:-

Thanks stephen.im getting the picture now.i see what that dude means by the inner balljoints(inner tie rod ends) .in other words if the rack to long,short,its not going to be in line with upper lower ca's  its going to be up the shit...Cool im Learning 

 

 

very helpful Dave.if that measurement is correct between the balljoints  540mm i can pass that on to Peter

Found another Rack and got my hands dirty,

 

and the measurements are more accurate now.

 

 

What is different to the other drawing is it's 515mm centre of ball joint to the centre of other,

 

and the  housing length 385mm:-

fantastic Dave.wish i could use comp better  to pass on your lovely tech drawing   haha

 

is that correct between distance to knuckles

 

    55----58-------------315----------------55      =  483 balljoint to balljoint ?   have you made an error or is it me

 

 

Oh its 85 .tutts

i cant see them propper thats not right also haha.i need some glasses lol

[N/A-PWR]

65-----385-----65 = 515mm 

no worries, my fault for not having it right the first go.

right click it and open image in new window.

Cool    not that it really mattered.main thing is your still correct in overall length between the balljoints  

 

thats handy... zooms in..i dont need glasses now .another likey

 

 

thanks Dave

Yeah, check to see if the previous rack lines up with upper and lower C.A.'s. Just to make sure you have zero bump steer to begin with; if not you can improve by getting a rack that's a better fit.

What you could do it get the measurements you require between the inner tie rod pivots and shop around for those that specialise in steering/suspension; particularly if they service a wide range of racks; they may be able to suggest what would fit. Of course the modern racks are likely to have power steering and you may have to look for LHD versions abroad; or you could target the US/Euro shops direct.  Custom suspension was a big scene here in the 80's; tubular components; re-configuring the geometry, etc. so there may be companies that could build you a custom rack; though I wouldn't know where to direct you, you'd have to do a bit of googling, perhaps ask those involved in racing, etc.

There's a mob in Parramatta that claim they can customise racks for conversions, etc.

If you're going custom, it may be an idea to consider a solidly mounted rack. Holden ditched the rubber bushes when they designed Phase II RTS for the UC Torana.

 

You can see the difference here; LH rack on top UC on bottom..Totally different mountings & bolts.
