At great hassle and expense, I have sourced proper NOS black vent windows and vent window frames for my bug.
I am now in the process of ordering the correct tube rivets to assemble the two but I need a rivet setter to do the job.

I have done plenty of research and know there are ways to do it without the correct tool but I don't want to go that way.

So the question is, does anyone have a proper tube rivet setter in Sydney, Wollongong or Newcastle areas?

Is there an 'Old School' brake/clutch service in your area ? If you can find a 'friendly' person, who has done a bit of brake lining work, you may be able to get them to do the job. Or borrow the correct tool... if they haven't chucked it away.

just use an Allen head bolt & nut

use a dolly n hammer and peen it over
