I have a Baja Warrior that I pulled from a scrap heap that was cut in half. I think I'm going to use the front fork and frame portion for a fat tire build. I have a 21x7x8 tire that I put on the front and have a new knobby 20x10x8 mounted on a 4/4 golf cart rim that I want to put on the back. Is there a double flange spindle out there for mounting a 60t sprocket and a brake shoe? I'm wondering if I have to get the ones I see on the net that measure 3" flange to flange and just cut and weld an extension. Any ideas?
