Welcome 865. Another West Aussie on the forum. Great to see. I have found this forum and its contributors invaluable in doing what you have done.
i bought a near complete (being very naive) A10 in the 70's. finally got into it and after 5 years work it has been a joy to ride since 2010.
Like you, from bits i have build a second A10 plunger, also a pleasure to have on the road. my 3rd (we all have addiction issues) from bits, is being road tested now ready to rego. my 4th is being dismantled ready to rebuild so that i know what i am going to rely on later.
a 5th, swinig arm (54) is hanging in the shed and in bits under the bench.
so lets know if you need any local info. Orabanda, as always, is right on it, Pablo at iron Horse is a great local souce.
As Peter has asked whereabouts in this wonderful part of the world are you?
