Rear Roll Bar Mount Measurements

[swooshdave]

I want to make a bracket that utilizes the three M8 threaded inserts on the rear roll bar.

I'm sure I wasted my time doing all of the measuring and the CAD data is readily available but I it did anyways.

Is anyone familiar with these measurements and am I off?

I'm curious if you refined these measurements after trying some things. I printed a quickie template to see how close they were and they weren't close enough for the bolts to go in. I tweaked them a bit and I'm printing a new one and will share my updates.

Yeah, I had to tweak too.

@ArtHughes Do you have some measurements you can share?

Yep I will pull them from my CAD later and reply back

104mm spacing, 9mm through holes to accept the M8 bolts (M8x1.25mm)

Also worth mentioning that they are rivet nuts in the frame, so there is some variance with how they center when compressed during installation. For that reason you could be on the safe side with one of your two mount holes being 10mm diameter, to allow for the slight variation that will exist in production.

Did you ever measure out the side bolt hole?

That's another M8 rivet nut... so anything up to an m8 x 25 or 30mm bolt would work there. It's a single bolt on each side so I don't have a distance measurement from another reference point.

I don't use the side bolts for any of my modifications so it's not in my cad design library.
