Not sure if anyone else is running into this problem but in AZ it is literally impossible to find the Losi spring cups for the 22 BB conversion. So I have found a decent alternative for people who just cant wait. I bought some of the older Losi spring cups like the ones found on the XXXT part #LOSA5079, and then I bought 4 of the TRA3768 shock collars. The spring cups are just slightly smaller than the 22 cups, so I took a razor blade and split the traxxas collar so I could fit it over the spring cup. Then I super glued the traxxas collar to the spring cup and cut the shaft opening the same size. Spring sets on it perfectly. Fits the AE shock end perfectly. Obviously its easier to use the Losi cups, but they are M.I.A. Out here. I will post a pic in a minute.
