Kona Explosif Cantilever problem

I recently started building up a 1990 Explosif. I purchased some XT cantilevers to put on there. I can’t fit them in the back. The posts are way to big. Posting pictures below of my break bosses, am I missing something?

Yeah, same levers for both. I've got a goat with Canti's up front & a XT U out back. Same levers. Same with an old Mt Tam I had with Canti's up front and a suntour center pull. Both center pulls and 2 bolt u brakes used the same mounts.

May want to hold off for more replies but I'm pretty sure it's all good

Yeah, I really don't want to screw this up again. So the brake bosses are in different areas of the frame for cantilever and u-brake, right?

Yes. U brake pivot point is different and a different size.

U brake pivot is above the brake blocks......cantilevers pivot below the brake blocks.....as seen in your picture.
