If I want to purchase a pioneer rhino rack platform and Mount it to aero crossbars, can this be done with this platform rack or do I need a different brand ?

Rhino Rack offers versions of their Pioneer Platforms that fit aero bars with the part # RR42114BF for a 48 inch by 38 inch platform or the part # RR42115BF which is 58 by 47 inch.

I lost my mounting hardware for my Rhino-Rack Pioneer Platform 44"x 37.5" that allowed my to hook it my default Toyota crossbars. How can I purchase more?

@ZR which one do you have specifically?

@JamesonC 42115BF is the unit. Rhino just told me they discontinued it and some of the parts no longer exist. I’ll be sure to never purchase any of their products again. That’s crazy that 2 years after purchase you can no longer get a proprietary part for this. Unit is unusable for me without it

@Zr That sucks to hear for sure. One of the reasons I like to recommend Yakima and Thule although they cost more is because they have replacement parts for stuff made decades ago. I know that's not helpful now but if you end up needing roof rack components in future that's what I'd go with.
