Sadly that's the biggest and most costly hurdle to get over when rebuilding these babies. There are new ones that are being made by a good sheety in Queensland which a few members on here have bought from. Basically better than the originals. I can put you on to him if you like.
Cheers, BB.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
