Just bought a '77 CB750 and was planning on making it my cafe racer project. I checked online for rear frame hoops but I'm not sure what shops to trust or what I'm looking for. Amazon has done for 30$-50$ but they're stainless steel and other shops have them for 70$-200$ so I'm a bit confused. Any help on where to buy or if it's better to make it myself somehow would be helpful. Thanks!
