9730 x 1. A new and more efficient Matrix, but it is 2.5inch deep (1/2" deeper than original) to fit into original Smiths heaters (with longer securing spring clips to sandwich it into the heater). For All models of  XK120  and also fits XK140 Drop Head Coupes and XK140 Roadsters. Comes with the correct securing spring clips supplied assemble it and the inlet / outlet pipes are in the correct position for the XK bulkhead holes ( as there are many other vehicle variants if your pipes seem to not be in the outside rim position)

NOTE : XK140 Fixed Head Coupes do not have enough space under the bulkhead. For XK140 FHC and Early XK150 you will need to fit the special build  2" deep matrix & clips, due to less space under these vehicle's dashboards. For these vehicles SEE 2" Matrix: 9726
