@Thevvy well not doing bad for an old fart mate, would guess I started my F&M apprenticeship just as you finished yours. Commenced mine on the tools in 1971 @ 17 yrs old.
The old grey motor was my first (FC wagon that grew into a RED mounted up).
MB a bit over the top initially but like most new gets easier _ Initially a bit daunting when you realize that there is a need to cut into the ECU/ECM harness. But comes together.
