Sherpa or prinsu rack help please

Ok so if anyone has one of these racks……could you please measure from the bolt holes of the cross bars down to the roof and tell me what that measurement is?

I’m looking at a side panel but don’t have the rack it’s designed for and need to see if mine will work.

Attached is the piece I want to buy but can’t get any info on.

 

Cant quite determine exactly which measurement youre looking for, but might this similar item help? The 6th picture has measurements and Victory's rack is quite similar

Yeah I didn’t explain it well haha. So the side panel bolts to the existing cross rails. If you measure from those bolts down to the roof line, that’s the measurement I need. I’m trying to see if the Sherpa or prinsu have the same height as my SSO rack to make these panels work.

 

I think this can be a hard one to answer as both racks look so similar. I'd say it depends on what you want, price or a slightly stronger rack? prinsu offers a fantastic price point, I own one, and it's one great roof rack. Sherpa seems better built and more solid, yet pricier. I do know their side panels are stronger, and I think another great thing it's it only adds 2.5" in height to the 4runner's roof, my Prinsu is leaning towards the 3.5".
