I can see there is 4 mounting points, as far as i know the tin tops did not come with space saver wheels (no Mk1's ive owned ever came with them) So i think the tin tops came with 4 straps that hooked into the center of the wheel.
Hmm the strap i found in my boot had 3 clips on it (should that be anchors ooo-ar) maybe one fell off or something
i've never had a space saver before either
