My customer sent me a Herald style gearbox tunnel cover he bought on ebay ..
It needed modifying to fit the A352 ...I had to cut reliefs for the fire extinguisher etc. but the main issues was it was 50mm to low at the gearstick.
I cut this section , splinted it with a 40mm gap and fibreglass the join...this allowed the stick to protrude through and the tunnel to sit down correctly ..
