A trip to sunny Luton yesterday the box and overdrive were rebuilt , thanks Pete . The refit now starts , called in to a local nut and bolt company asking for a solution to the Overdrive Solenoid . One of the fixings , a 2ba screw is nigh on impossible to remove without taking out the gearbox and overdrive . The right hand chassis rail is the obstruction . The solution is a 4ins 2ba cheese head screw which will need trimming . In future the solenoid can be removed without taking out the box . In due course will advise final measurements for those interested
