Can anyone tell me if all those overdrive springs will be freed when I unbolt the Laycock de Normanville from the back of the gearbox on my 330 2+2? Last time I did the overdrive on a 250 I had to use the weight of the gearbox to compress the springs on reassembly. Maybe they made a better solution in the 330. It appears to have a plate between the two units. I don't want to disassemble the overdrive; just replace one synchro (2nd) in the gearbox. Thanks, Art T.
