Replacement sadly, basically it's a hexagonal aluminum bar that is threaded on one side and reverse threaded on the other, those screw into the middle of 2 high strength steel bars that attach to the front struts. I haven't accurately measured it yet but I'd guess that since it's from Japan it's metric. It worked before it was shipped and when I got it it was locked up tight. Box looked like it was supported on both ends with something heavy in the middle (ie folded into a "C"shape lenthwise.) Unscrewing it basically crushed->stripped completly the threads for about 1/4 inch on one side and close to an inch on the other. I could probably cut the damaged threads off but I'm worried about the stability of the bar losing that much attachment...
I'll see if I can get some picks up later....it's not a happy
