Over on the H.A.M.B. nailheadroadster made a number of posts in the summer of 2018 outlining work that he did on his 29... with a very detailed description of how he lowered his car including pictures and a parts list.

Here is what he used for the front:
1) 33 Ford axle
2) 32 Ford spindles
3) 32 Ford spring perches
4) Posies 2" front lowering spring (part # 1002L)
5) Stock Model A Ford kingpins
6) Stock Model A Ford brake actuators
7) Stock Model A Ford shackles
8) Stock Model A Ford wishbone
9) 1/4in spacers (2) These go between the TOP of the axle and the wishbone (VERY important!)
10) 32 spindle bolt bushing (reamed to spindle size after installation)
11) 32 spindle bolt rebuild kit, with new bearings
12) 1 ½” shorter pitman arm (this is not required, but definitely helps to ease steering effort)
In the back he used a Model T spring with couple of leaves removed off the top and a couple of alternating leaves after that leaving him with five T leaves total...
