I thought I would throw this up here in case it could help someone out someday...
I broke my dead pedal at the last autocross and I just received a replacement from Sunset Imports in Oregon :
Part # 996-551-611-00
List price $7.79 - Sunset price $5.55 ( plus $8.45 for shipping )
The cheapest part I have ever bought for the Box !
I am still considering these :

( but I am wary of attempting to drill through the pedals )
