Ok now..From what I have learned is the 92 secondary uses it own type of shoe's...93-94 uses a different type and cheaper...And yes the 92 shoes you could still get but are VERY expensive...Reddy,sounds like the shoe's you got will only fit 93-94..There is a shoulder height difference between 92,to the 93-94.....But for the most part I heard the 92 secondary is the best for drag racing not trail ridding..
