OP's bolts will be 5/8" for the radius arm and the axle end of the
rear arm. The panhard rod bolts will be 9/16", I think.
The difference between 5/8":M16, and 9/16":M14 will not matter as far
as the bracketry is concerned as it's probably worn anyway. There is,
I think an issue with the bolt size and the bushes e.g M16 bolt won't
go through the early bush. Get the bushes first and find suitable
bolts afterwards.
It mattereth not whether it's UNF or UNC provided the bolt and nut
threads match. LR used UNF for what it's worth.
Phil's comment about not taking the side load on the threads is valid.
If you can arrange the grip length/spacers to avoid it it's worth while.
