There are some really nice details on that Badster thing... Well its just bloody lovely to be fair!
Made some more progress on mine.. New wheels fitted after waiting what seemed like an age for the wheel bolts to turn up..
Front 'extension / vent' on fitted to both sides, though they require tiny bit of fiddling to match but thats no biggy...
At the rear, the new wheels have 20mm spacers (as do they front) and the rears would have caught the bodywork under severe cornering / compression etc.. So, wheel arches required to be bulked out a bit... There a copy of the existing arches, flexed out where required, riveted on, glassed it etc.. and then i'll cut out the existing clam where required beneath. In the area to be flared out they are unsurprisingly 20mm wider...
When the photos were taken it had the standard rear billies on, hence why there is such an arch gap!
