I've looked all over the web and cannot find specifics on what size the thread and spline count is on my 85 hj60 I would like to buy some billet aluminum window cranks, that are universal sized. But I'm not sure what size and spline count the original equipment is. If anybody has this information for me it would be greatly appreciated before I order these semi-expensive window pranks and find out they won't fit. I am in Nicaragua, so getting them here is another problem but I've got that dealt with. I just don't want to find out they are the wrong size after jumping through a bunch of hurdles to get them here.
