If we dont have the info you need...
 
Try getting in touch with Nathan Peta, Ken Oath Kustoms.
 
On here he is... Not Even.
But his profile hasnt been logged into for ages, so maybe a PM as it would prompt an email alert.
 

 
I believe he was doing a steering rack conversion to his 1000 ute.

Spent some time in both of those threads previously
One Corolla and one Starlet... but no specifics of the actual models of vehicle or completed setups.
Not sure on the front rac setup though Luke with an A series as theres not much room for a sump
And while I've wanted to do a dry sump setup for awhile.. .and already have pan , pump etc. I'm starting this build off easy and will improve it once everything works.
Then other pics show it rear mounted... so not sure where your at with this.
 
Only at the gathering parts stage atm... honestly I've never had any issues with the old steering box setup on my racecars
But always looking for a better mouse trap (less joints to fail)

I have often wondered what would be involved in a complete steering assembly from a roadster into a 1000.
 
Wheelbase is same to the mm and from memory track width is within 10mm.
 
Would be a good starting point for stiffer front everything.
 

Ash, the Roadster front end is as heavy as the bluebird 411 stuff and virtually the same bar disc brake setup
The later vanette is very similar too 78-87 I think and Neil if those Mustang and other Murican A arms could
fit youd save alot of trouble and moneys but luckily only A arms are at the top while the bottom is a single
units which could probably be from something aftermarket and adjustable.
You could run Mazda series 5 onwards alloy units on sleeved original uprights for that 114.3mm x 5 stud pattern
or maybe some other alloy upright with the mustang aftermarket tubular A arms
