TR Gearbox top cover selector rod interlock issue

Hi Folks,

we (me and the owner have a top cover from a TR gearbox. I believe it an early(ish) example as it has a 7mm thick front flange.

The standard 3/8" diameter balls (Moss P/N  BLS112) for the selector rod interlock do not fit into their holes in the webs between the rods.

Item # 45  Balls

BUT more puzzling there is no way that the holes for these balls could have been drilled as there are no

access holes (with core plug  Item # 28 with above link) on the outside (typically where the reverse lamp switch would screw in).

Question 1 - were these top covers ever fitted with smaller balls.

Question 2 - has anyone come across a top cover with NO access for the interlock web holes to be drilled.

Hi Folks,

 the answer turned out to be simple. 

The original access holes to enable the drilling of the interlock holes in the web had been filled with an Ali plug then smoothed down - aaarrrggghhhhh

Once access was gained the interlock holes in the webs could be cleared to allow the balls to fit.
