I just hunted for my bookmarks on RHD 914 conversions that are on here with other links, but can't find them quickly right now.......must be my half-zymers kicking in!
The factory never did any RHD 914s, although the steering gear etc. are clearly set-up for them to do so, and the books on the 914's history indicated that they intended to do so eventually - had production continued & grew, rather than shrunk after 1974, and a few other factors.
There was a UK company, Crayford IIRC, that did aftermarket RHD conversions on the 914s for the UK & more limited outside markets (a few made their way down-under to the land of OZ). Unfortunately, the cost of the 914 + UK tariffs/VAT/etc. + the RHD conversion jacked the price up higher than a new Jag XKE, so they weren't too popular even there.
There were also some privateer RHD conversions.
EDIT -
HA!!! Found it!!!!
