Rear control arm threads

[Blitzed]

Hi All,

Took on the huge task of replacing all my suspension bushings (rubber). Front control arms tough but no issues. The rear control arms have been difficult. 8 hours to remove the pivot bushings at the forward shaft. Upon removal of the second bushing sleeve, stood back to pat myself on the back and the control arm fell out of the vise and donked the tube for the slide on bushing (24MM bolt)

Does anyone know what tap size is needed to clean up the top threads in the tube?

Note to self,  leave bolts in the tube on the next arm.

Thank you,

The tap you're looking for would be a M22x1.5   a cheap tap will clean up threads but if the "donk" is too deep even a quality tap isn't going to do the job, a tap can't push out a dent in the threaded pipe.
