I had some complications withe the previous arm on the bike with the alignment. Talked to Larry many times over the last few week and we decided today I was not going to be happy with the previous arm. He exchanged the chromoly arm. But with an aluminum arm with bracing inside, 4 pound nitrous bracket. Tire hugger mount, and always air tank and chain guard mount. This was an even swap. The arm I had was new but I did not buy it. Was on the bike I bought. Thats good business. He didn't have to do that.
