i use vise grips to crimp it on. do you have brake spring pliers?? if not get some they cost about $10 at nappa and are worth every penny. what i usually do is hook up the parking brake lever(horse shoe thing) and put the lower spring in that ties the shoes together and put the adjuster linkage in place and the spring for it, next position the equalizer bar, and spread the shoes apart and put them in place, next put the pins in the backing plate through the shoes and install the clips that hold them down. now turn the adjuster in all the way and put it in place, push the shoes against the wheel cylinder to push the pistons in as far as you can, now put the remaining springs in. now all you have to do is adjust the brakes, this is done with the drum in place and the rubber plug on the backing plate removed, a small screwdriver works for this but a brake spoon is recomended. i usually adjust them up untill the drum is locked up then back it off just untill it turns freely, you need an extra screwdriver or pick to back it off by pushing the adjuster lock away from the star wheel while turning it.
