Peter, not sure exactly where to get Track Rod Dust Covers, but the site linked above has various different sizes and a handy chart to work out what size fits what. Measure the ones you've got, then get any generic cover that will fit. My local indy garage was very helpful and happy to supply them to me, also the local carparts shop (proper old style one) tried with various boot sets so possibly one of those would be suitable.
