I got a set from David Silver Spares for my 74 550. Cost me $40.67 based on the exchange rate on 2/19/09 when my credit card was billed (I'm looking at the credit card statement right now). $40.67 included the cheapest shipping option they offered to have the parts sent to my house in Kentucky. If I remember correctly, took about a week or so to get them. They fit perfectly, and pricewise were comparable to 4 pods @ $10 a piece from my local motorcycle shop.
