Well the 050-4035-00 is actually a Hydro Gear part for EZT transaxle. Should be HG 70865 kit which under $9 or you could just get just the brake arm itself, HG 52367, which is around $5. Personally I have one 70865 in stock. But I also have it in a 71356 kit which includes a spring. Now the BB part does comes with what appears to be a longer screw. Just reuse the current screw and some Loctite. I don't have a BB HG model number to work from.
