Nothing particularly wrong with LHD, it just doesn’t work for me.
Are any of the parts you listed handed, or is it a case of reversing them on the other side?
I have found my dream bus that is perfect except 1 point, it’s LHD
Apart from a RHD beam a welder and a hole saw what else would I need?
What parts are interchangeable?
How difficult is it?
TIA
