I'm sure there's some sort of write up somewhere if you look hard enough...
Should be pretty straightforward & time-consuming tho...
basically, you need all the rhd stuff - i.e. dash, powersteering rack, brake lines, etc. Then it's just a matter of doing it.
Should be a lil easier if you have a rhd front-clip to take parts from.
As for "is it worth it?"... what is rhd worth to you? It's not gonna make you a better drifter or whatever just because you have rhd :p.
* and I just did a quick lil search for "rhd conversion" & looky what came up as first result:
zerothread?id=268974
Should give you a good idea from looking @ the pics what needs to be done.
Next time, search NOOB!
