Shackle plates - which one goes where?

About to start building my 1971 Series 3. Got all my new shackle plates and bolts but have no idea which one goes where! Some are threaded, some are not, some have a wider "offset" than others, some have no offset. Ordered all the new bolts also, some linger than others, no idea from the drawing of what goes where.

Can anyone help?

threaded hole goes to the spring and on inner side greatest off set is front to make up for width of chassis the bolt goes through the non threaded hole then spring into threaded hole then nut

Excellent, thanks for the really quick response! I take it I should be able to work out which bolt length goes where unless I'm dim (may be the case!). Also do I just apply a good coating of grease to the bolts, plates etc.?

i would coat the bolts

Take notice of JM, lad.
