Gen 3 426 into aussie a body

Good point Bakerlite , having the engine centered does not necessarily put the whole engine in the center of the engine bay . However there is some room in the tunnel to get it close , or center with some creative clearancing , the RHD Big Block guys do it often .
Also the K set up I showed does have some adjustability , one should be able to find a happy compromise .
Alot depends on the trans you want to use .

First of I will say I was impressed on the quality and price of the HDK set up , and was considering this for my car , however as you state , the cost of importing puts it out of reach for some people .
Our RHD steering box mounts on the inside of the right chassis rail (picture )

The steering is really quite different from the LH version. Not just a reverse mirror of ours. Actually it tucks more rearward and out of the way.

Thanks for the compliment.
Someday we will get this freight business handled to be more economical for you guys. I'm thinking a container to hold a half dozen assemblies. I live close to a major air shipping hub.
