New Mounting Hardware for Factory Crossbars for Thule 600 Rooftop Cargo Box

Question:

Have a 30+ year old 600 pictured in https://www.etrailer.com/question-249184.html. However looks like I need mounting plates with holes 5 3/4 inch spacing to fit around the factory cross bars and into the holes inside this very old but heavy-duty Thule box. Might you have parts to fit?

I do have an option for you but it may require modifying as we don't have any replacements parts for the Thule 600 Rooftop Cargo Box. I recommend the Replacement Mounting Hardware for Car Top Cargo Roof Cargo Box part # CTC-18PARTS which works with most factory crossbars. You'll likely need to drill new holes into the bolts for the u-bolts but aside from that it should be a straight-forward install.
