Slip over cab support cover

[phlegm]

Hi guys, I have done some research on here and fully understand that in most cases when u have a cab support rusted out there are larger issues. In my case however I believe I can cut out the cancer, hose it down with inhibitor and then put in the slip over.

Couple of questions, has anyone put one of these on? Do they just bolt over or are you suppose to tac them in with a welder (I dont have one or the skill set).

Looking for some experience before I order the part.a
