Craig, information I have read in regard to ADR compliance back in the '70s is that manufacturers didn't have to prove to any Govt body that their vehicles complied with the relevant ADR's of the day. If the manufacturers R&D showed complete compliance then they were allowed to fit a compliance plate. Manufacturer's have always basically been able to do whatever they want as long as they prove unto themselves their products comply with the relevant ADR's.
In the building industry it's called self certification, in the Auto industry VW call it cheating.
That VW comment is funny Dave - credit to you - genuinely funny.
Your point on self-certification is exactly mine - GM-H seems to have self-certified - no issue - and yep, fit the compliance tags themselves as they would have or perhaps even continue to do without hindrance.
But, and I come back to this - they must, must, must have been obliged to have 'lodged' that self-certification in order for it to have had an effect - a legal effect if you will.
And that lodgement (I expect) is where the substantiation (or not) of any evidence exists as to the abilty to install a 308 V8 into a LJ per NCOP.
Notwithstanding the wonderful research that has portrayed that indeed GM-H did build these cars and perhaps even some survive today, nevertheless, the onus will rest on the person attempting to register a LJ with a 308 to provide that documentation - the self-certification/lodgement documents either issued by GM-H or received by the regulator of the day - eithher end of the equation will do.
Al has come a long, long way, and I reckon he is very well placed and sufficiently tenacious to attempt to achieve this outcome given the significance of that car and the emphasis placed nowadays on nostalgia - surely GM-H are keen, indeed very keen to participate and see this to fruition?
Cheers, TB
