Rally Dash, modern interpretation

I have my dash out and completely apart. Using an Exacto knife and a razor blade I was able to successfully trim the ends of the little plastic posts that
hold the gauge assemblies in and the gauge lens assemblies together. I am probably several days away from putting it all back together, but I am thinking of the
re assembly process.
How to remake the ends on the plastic nubs,,,, I am thinking of using a dab of silicone on the nub ends. Think that would do the job?
What have others done?

thanks
