I don,t understand why this problem has occured
But how about removing the tube in front of the gearstick ( TT5 ) & reposition it an inch or two further forward so that its between TT9 & TT11 tho I appreciate it means cutting some new steel, If you did this I would also suggest putting an extra piece of steel behind the gearstick between the 2 TT7,s to ensure the strength of the tranny tunnel is maintained.
As said ....not sure why this problem has occured but if you can,t get the engine any further back then I,d do the above suggestion.
cheers
