subframe connectors

What would be the shipping charge to Washington state (98664)..? And I'm talk'n el-cheap-o in a mule drawn cart, ha, ha... If you (anyone) know, then please share.

They look plenty stout and fair priced for sure.
Would these fit my 72 Duster..? Maybe that's already been answered in here & I missed it.

many thx. Craig ~
