Series one 2litre petrol LPG conversion??

has anyone got any advice or experience of converting a 2litre petrol engine to run on LPG?

i suppose i was planning on some kind of DIY kit - i know quite a few have converted 2.25 petrol land rovers, but i'm sure sure where to start with my own SWB series one!

any ideas folks...

Problem with DIY LPG conversions is getting it insured, they'll want it inspecting and certifying.

Then the problem is finding someone to certify it, as they want the work fitting it...

That was the general consensus when I last looked into it anyway
