Hawk suspension

[gtmpaul]

Do anybody happen to know the sizes of the rose joints for the rear wishbone inner mount, and the track control arm hub mounting?
I've been hunting a 'clonking' sound for about 8 weeks now, yesterday I finally managed to get the car into the air, all four wheels off the ground. The source of the mysterious 'clonking' was immediately obvious, both are gone so need to be changed asap

I would say wishbone inner 1/2 x 5/8 unf, track control 1/2 ×1/2unf for the front connection 1/2 x 3/8 for the rear connection, but I would need to check the rear one.
