Clutch Cross Shaft Pivot Stud to Engine

[Kevpix]

Hi. I've been taking up some of the slack in the clutch cross shaft linkage ("70 C3) and noticed the shaft to engine pivot stud is loose. I can nip it up but it then becomes slack when pressure applied. I guess the threads in the engine block are worn. I've measured my replacement stud and it looks like 1/2"-13 UNC.

Is this common? Has anybody fitted helicoils?

Rather a shallow tapping to drill out for a helicoil. What about chemical metal or similar? - could you get access to drill oversize?

How about trying first a quick fix using a Permanent Strength Anaerobic Threadlocker ?

Got to be worth a try. I've used Loctite 270 and 638 on similar applications in the past and they've worked very well.

Is the thread worn on pivot stud? Meaning with a new stud thread would it hold tighter? Or if no one is looking PTFE tape.
