80 series brake booster for the 70 series but calipers are used from the early v6 4Runners , I believe 80 calipers do not work unless maybe from the early models with smaller front discsIt was @joekatana that told me about the 80 I think. The calipers for mine are NLA and thus I need an alternative. I’ll order the 80 series one and compare. The dealership said I could return it if it doesn’t match.
