Unless you're going for nostalgic parts. I would order empty tubs and top plates from Dash Motorsports. Dash also has tons of coloured delrin gears at 4 for $1.

Then add AW arms, magnets, and anything else you got laying around to complete the chassis. The Dash wheelbase matches Aurora perfectly. Just an option.

Wizzard also offers an empty chassis. But they are $12 US.

Many old Aurora's are worn out by now.
