[Pro touring camaro]

I bought these shock with the front subframe and fear quad link and the rest of the DSE stuff for s first gen Camaro about 10 years ago. The car is almost finished but the fear double adjustable cool overs are leaking oil profusely. I called DSE and they told me that Speedway. Now owns the shock manufacturer but after waiting on hold for the better part of an hour twice with speedway i decided to try to find out who made them and try to contact then directly yo see of i can have them resealed. They have been used. Thanks for any info
