Get well. I hate colds like that. Thamnks for making the stretch while feeling ill.
nm9, MP did indeed sell this fixture. Good luck on finding one now. That may be impossible.
As you can see (And I'm sure you already know....) the huge oil hole in the lifter bore. This is a serious issue on high RPM engines. Along with the blocks internal oil passages that should be enlarged and smoothed. Blocking the drivers side oil feed at the blocks front also should be done.
Now you could run a roller cam without these mods if the RPM is low and the lift/lifter body doesn't have an issue uncovering the oil holes to bleed out and drop pressure like a 2 ton heavy thing falling outof the sky.
