I plan to do a fire wall cut and weld. the panels are the same shape for both RHD and LHD its the hole pattern that is different. The heater core holes remain the same the issue is the support of the firewall where the pedals bolt to. it needs to be moved from left to Right to fit the heater core properly. I haven't pulled the motor yet but when i do i will make sure to post comparison pictures for others reference. This site is full of knowledge if you search you will find almost any answer you can imagine.
