Could somebody post a pic of factory 1968 Chevy C10 lower shock mount and stud

[HeavyHauler]

I was getting ready to install some custom Bell Tech shocks on the rear of my 1968 Chevy C10 short bed and the lower shock stud is too big for the shock eyelet.

Are the factory lower rear shock mount studs removable? It looks like somebody may have done some welding and added bracing on my lower shock mounts but may have used a larger stud.

Can somebody post a pic of the lower shock mount and stud and possibly get me a measurement of the stud diameter where the shock would sit?

The Bell Tech Shocks I am using were recommended by Bell Tech.
