RB 12mm Extended Sandwich Plate

The lower section of this 12mm extended RB sandwich plate is contoured to the RB26 sump & 5 speed gt-r gearbox bell-housing and is produced from 2mm Carbon Steel with a zinc plated finish

Optional 5 speed gearbox extension
20mm thick aluminium bracket to suit rb26 gt-r 5 speed transmission bell-housing, This additional aluminium bracket is to be welded onto the bell-housing, this allows for the original bolt holes to be shifted/re-drilled and tapped up to 12mm lower depending on what brand block brace is being used and what thickness it is.

Alternatives to using the weld on aluminium extension ( Best method when installing with a 6 Speed Getrag )
Weld the original sump holes closed and re-drill the holes higher up on the sump, then you can reuse the existing gearbox bell-housing holes bolts instead.
