This is the proper bolt to use with the main fitting rubber bushing holder.
 Button head internal wrenching  3 inch long 1/2  - 13 and castle nut.
Gives the maximize room for the upper link rod ends.

You need top drill the bolt for a cotter key after you install the mount.

We include the bolt and nut  now with all the main fittings. You can get them from
Macmaster Carr if you already have a Uni Mount.

Alex. you are getting them with your new main fittings.
