https://www.trademe.co.nz/trade-me-motors/motorbikes/parts-for-sale/batteries-mounts/auction-3309821723.htm saw this if of interest
Starting bid $200 Yikes!
If good replicas could be made, the cost might soon be recouped and that one could go back on sale.

im pretty confident in making the moulds and the final assembly but $200 is a bit out the price range at the moment.

G'day 865.
In the not too distant future (hopefully) I'll be pulling down my plunger for rebuild. I could loan you mine.

Hi Pete,

How ironic. I started this thread a few years ago and it looks like its come full circle in my own back yard. I have the required air box in my shed, not yet in use. So I will drop it in to you in the next few day as you are just up the road about half an hour away. Could you please PM me your address mate?

That would be the forum doing what it's designed to do.

Update on airbox. Have almost finished the plug to take a mold from, just a bit more hammer work a spot of welding and some filler to round the edges. As well as do the angled drop off for the rubber manifold insert .Battery strap/mounting bracket about 30% done lol
Because I'm making a plug the overall size of the plug at the moment is around 2-3mm smaller than the original to take into account body filler primer paint etc. Once it is ready to take a mould from the dimensions should be on par with the original. I'm probably going to make some modifications to the air filter area so a modern foam filter can go in. Any suggestions please feel free to weigh in.
Cheers

I have an original air box complete with a volks air filter the only thing missing is the Battery strap which has been chiselled off, if anyone would like it, I am willing to sell it to the highest bidder, PM me with your offer.
By the way, I have just reduced the rocker box gaskets to £18 a set for member on this site.
