Pivot ball bracket for a ‘68 Dart

So I completed my 4spd swap in my 68 Dart. I plan on making a post about that separate of this but.. could I make a 20ish mile drive before it gets welded on to the rail? It’s a diaphragm McLoed rated for 400hp so it’s not a super heavy duty clutch.. I just need to transport it from a friends house to my house. Def not ideal but.. I didn’t wanna have to tow it. The buddy who helped me doesn’t now how to weld and neither do I. Once I get it home I can bribe someone to come pit some fire on it..it’s bolted into place
