ford 6610 gear linkage

[Mr Echomax]

Hi I have a 1982 FORD 6610 with worn column gear linkage - can anyone suggest any remedies or where i can get replacement parts

what is worn, is it the modified h pattern shift or original rubik cube, if you remove plastic covers and metal plate at bottom of cowling you will be able to see linkage something may have come loose, i will try and find diagram showing parts.
