Toytec boss erosion

Hey I was wondering if you guys have ever had a problem with the toytec boss coilovers eroding? I bought them hoping they would last a long time but my stock cheapo Amazon struts lasted long than they did. 1st problem I had was the adjustment ring and locking ring gaulded to the threads and yesterday I noticed a tiney pin hole had went all the way into the body and now is leaking oil out. I bought a new set of OME ones but id like to know if there is a way to get a rebuild kit for the toytecs and after I get it torn apart I could weld up the pin hole. I planned on calling toytec today but figured I'd ask on here and see if anyone has gotten a rebuild kit somewhere.
