and not just the brakes, you need something to mount the caliper to....so hubs from the 33 or later sprint will need to be used
and then the sud struts won't bolt up to 33 hubs either eh,
so its 33 front suspsension legs, the 4 four bolt strut top type,
33 hubs, discs, and calipers, complete
and if you are sourcing the parts from a donor broken up 33, the driveshafts might be an idea too depending on your discs flange set up.
and don't forget that you'll have to route new brake pipes through to the inner wings instead then too.
so just get as much 33 front bits as possible, then its just a bolt on job, nothing to fabricate or make.
plus you can go BIG BRAKES then too!!!!!
all the best, good luck
