Maybe I'm misunderstanding the question. Are you looking for a crossmember that works with the DSE frame for a TR6060?
I dont know specifically for the 6060, but my T56 Magnum works well on the hooker blackheart crossmember in my DSE frame.

Can see it a bit in this pic (old pic so can get more recent if you'd like).
