Help Needed to identify Steering Rack

[Art Racing]

Supra race car has had the original power steering rack removed and a manual rack put in instead. The ratio is way too low for my likeing (more than 3 1/2 turns lock to lock) so I am looking for ways to modify it (ie a quick rack or similar). Trouble is, I don't know what it is. It is a Toyota rack, and mounts up to the car perfectly except for the crossmember is modified on the passenger side to move the mount on that side another inch or so towards the centre of the car. Have attached a couple of (poor) photos, but was hoping someone could identify what it comes from. RA60 perhaps?

Since you have moved the passengers side mount, I'd be looking at something in the RA60/SA63/RT142 type range yes.

Can't personally verify it for you though.
