5 lug conversion questions

Hey guys, I ran it to some problems with my 5 lug conversion. Two of the dust shield bolts broke off in the caliper bracket on the passenger side and 1 broke off on the driver side. Should I drill it out and tap it for a bigger bolt or just forget about the dust shields all together?

Also, how do you remove the ebrake cables from the drum brake?

Nothing ever seems to go smoothly. Any help is appreciated.

Thanks!
