I need some help please

Hi I am looking for an emergency brake assembly for my 75 scamp. So far this is all i have found.

Is this the only place I can grab these cables? Im kind of hoping there is a cheaper alternative because there cutting hours at work and I don't have a ton of money but I also know brakes are important and I do not want to skimp out on them.

Thanks,
Joe


P.S. can someone please point me in the direction of some 3" studs that I am going to need.
