Rain tray replacement?

[nealtovsen@yahoo.com (Neal)]

Anybody got any bright ideas for replacing a Mk1 rain tray that is cracked
and has holes? Mk1's seem to be non-existant in the junkyards around here,
and it doesn't look like a Mk2 tray will fit well.

If it ever happens to rain at an autocross (that never happens, right?) I
don't want to end up sucking water into the fresh air fan...
