TTI headers in right hand drive abody

hey all,
iv got a 68 4dr valiant running stock auto 727 and 273. Cause im in australia its right hand drive and nothing i could find about tti states whether it will fit, was wondering if any of you in ur travels had heard if they will or not cause from what iv been reading up on they are a pain to install in LHD so im a bit sceptical. pacemaker are the only company iv seen that confirm a fit for rhd. thanks in advance
