Losing motivation to have another crack - didn't round the bolt second time round - I'm starting to get a feel for "this dirtbag ain't gonna budge" prior to the bolt rounding.

I've had a look into dodgy ways to fill the gearbox too - I haven't been able to sucessfully get any transmission oil into the gearbox through the hole where the gear stick usually goes. Going to be real hard to get it through the breather pipe - would need some hoses or pumps.

Last one I just thought of tonight - if I lifted the car up real high at the back, removed the tailshaft from the back of the box - couldn't I fill it up with oil out the back of the gearbox? I imagine this one will work - haven't piloted it on the dead 60 series box yet....just thought I'd throw it up there if anyone had any thoughts...
