I got some FJT custom length H beam rods along with YCP Vitara pistons. The rod strikes the underside of the piston when moved side to side once mounted on the pin. I am able to force it to move, but its still obviously a concern. Should I use a grinder to flatten the bottom underside of the piston some? Has anyone else ran into this problem using this combo?

 

could you maybe take a few pics of this? ive done a lot of eagle/vitara setups, and a few fjt rod/vitara setups and not really ran into this?

 

i used the same setup on my y7 ran into the same problem so i ended up grinding the edge off. im not sure why they have that like it is
