early A slant header

Why hasn't anyone (or has anyone) bothered to do a run of replica Hyperpak headers? I'd love a set for our 64 Dart. I'm in Australia and I'm really stuck for decent manifold choices, all the tube-headers (as you guys call them) make me nervous as to whether they will fit because our car is still left-hand drive. I'll be watching this thread to see what the outcome is.

There is a member over at slant6.org who has a set of the Hyperpac exhaust manifolds and is planning on getting them reproduced if there is enough interest.

There is an Aussie company reproducing a close copy of the old Clifford long tube headers designed for use with power steering. And of course there are the Clifford shorties for use with manual steering.
