Depends on the crossmember & rack you're using.
Early rack/crossmember use those & deal with extractor clearance with alternator/bracket + rack near the sump
Or later rack & crossmember then cut battery tray for clearance...essentially vn-vs underneath.
Had vh crossmember,powersteer with modded aircon bracket for alternator to clear extractors but still touched rack where they go near sump...ended up going manual steering instead of changing everything over to later model vn-s underneath.
