Im at work and need help.... does anyone know the size of the two threaded bolts on the front subframe that bolt up into the boxed firewall area, and the sized of the thread of the rear suspension springs that go through the wheel arch into the boot?

I need to make a trip to the hardware for a new painting frame, but dont have the details on me
Thanks

Front subframe tower bolts are 5/16" UNF.

Rear helper spring threads are also 5/16" UNF, with Nyloc nuts.

The subframe tower studs are stepped - they take 5/16 unf nuts at the top, but the threads in the subframe itself are 3/8 unf.

But if they are bolts like mine (hydro, as he has rear helper springs) not studs, the tower threads are 5/16" UNF.
