Can anyone recommend a centered rack and pinion steering rack that could be used in both LHD and RHD configurations, also with power steering (will be electrically driven)?
The Porsche 911 racks are centered. I think they were also used on the 914's. I don't know how long they are though. They show up on eBay quite frequently. Most of the racing supply houses will supply custom length racks brand new that are centered too. A great option if you don't mind spending a little more.
Summit Racing has a "Universal application" section of their Rack and Pinions, but they all look like LHD Ford racks, so I don't what's up - maybe call them.
There must be others out there, I just don't know of any off the top my head.

Try Coleman Racing, I believe the site is colemanracing.com. I believe they have racks that have extendable ends to space the inner tie rod pivot to your desire.
Good luck
