AutoVation now has the group buy available for the 79-83 pedal covers. I believe SMNC is still working with AV on getting the S3 pedal covers, but I'm not sure what the status is. The pedals are drilled and the covers are bolted on, so they are very secure, and grip your shoes suprisingly well. The first 3 pictures are the S1/S2 covers. The Group Buy ends on Dec. 12
