aluminum swingarm chain slider

Upon trying to order a chain slider a year or so ago I was told there wasn't currently a source. My glue to the swingarm repair didn't last very long. I ordered one for a 1999 te410 which strangely is the same as for my 1998 wr 125 which seems still like new. If I had to do again and I will order another one next time I order stuff as these things seem to break as pictued I will put the lower bolt or screw in first in the corner of the oval hole and only splice the top as I started off the old one instead of the bike with my mod.
