Just putting this out there for those of you thinking about this swap. I bought my brackets from SKY off-road. Quality bracket and overall happy with the service. Before you do this swap make sure you have the correct brake lines because trucks and blazers after 1979 use a 3/8 brake Line bolt to caliper. Pre-1979 uses 7/16 so source the lines before you do the swap. I am trying to do this right now. I guess what the problem is when you call these companies for technical info on their product they have no clue. Also beaware you may have to recess the holes on your brake rotor cause the stud can crack the rotor. ( I have already cracked one pressing in studs just 2days ago). Called sky and they said use a different size stud but the number they gave me the stud just fell in the holes. Called them back and they said drill them out. It is getting very irritating that your spending hard money on products that the manufacturer knows nothing about. I’m good with my hands so I’ll make it happen but just don’t lean on companies for answers... it like asking a child why they made a mess!!!
