I agree with 'me'. :-)

Nah ...
I'd start from 'scratch' ...
dumpster dive at the local Steel Shop ... I do.
Hand 'carve' the plate, drill to accept the OEM fasteners ... 'mm' mach
screws .
RE_use the mm mach screws.
30 mins time.
find a 5/8 ... 3/4" dia "rod_stock" of plain brass ...
local mach shop ,
2" long +\-,
braze the plate to the 2" lgth of rod stock ...
rod =centered= on the plate , pleze.
The two(2) mm mach-screw holes, and the 'drilled' hole
aught be =on= the same scribbed line , equidistant twixt the mm
mach-screw holes.
Center-punch a drill starter 'dimple' in the plate ...
after =accurately= locating same ...
a steel-use, carbide scribe wll help immensely,
scribe_lines done in/on a "blued" surface if you're finicky.
"blue" is a canned, blue, quickdry, steel 'lay_out' ink.
sharpen the dimple punch to a point ... so it "hurts'.
*If* your accurately 'scribbed' lines are crossed at the hole center,
you aughta be able to 'feel' when the punch "drops" into the crossed
scrib lines, in the steel plate ...
whack it. Helps start the drill accurately .
.............lathe drilling -
chuck the brazed assembly in a lathe, 1/8th inch drill in tail-stock ...
drill a 'long' hole , with a =properly= sharpened, long-hole
'sharpened' drill ...
.. get the lathe owner to sharpen it ...
"this" hole aughta fit a short piece of 1/8th inch steel drill_rod ,
similar to the OEM TA 'piston' ...
no reall need to be exact ,
the object is to have the 'piston' 'hit' the internal lever on-center
....
Proceed as 'with' a top_circumcized 'TA' ...
Again ... dont forget the cable_clamped, dirt seal at the juncture of
cable-entry & TA top .

Will email my addy.
All too simple to construct , even from 'scratch' ,
just using 'words'. :-)
When you're 'done',
you'll have a flat spot in your forehead ...
.......................
As an 'alt' to a lathe ,
chuck the brazed assembly in a BIG_HUGE( BH ) drill press vise ,
drill successively larger holes ... 1/16 ==> 1/8 , in 3/4" to 1" depth
=steps=
to completion.
The 'BH' vise resists the drill's 'grab' in brass , more better_er
drilling.
Drill Press 'quils' wobble far more than a lathe chuck ... very sloppy
....
thus the need to drill in 'steps'.
............
Make =sure= both 'sized' drills are ground such that the flutes are
symetrically
ground,
and that the 'pointy' end is =centered= in the 'root' of the bit ...
.... "root" = the 'thinish' drill section twixt the flutes ...
.... aka the drill's 'web' twixt the flutes ...
viewed from the cutting end .
The pointy-end wont quite 'be' a needle point ... more like a =small=
chisel end.
...........................
Drills, ground off-center, drill a larger than 'size' hole. ;_(
.............
Make =sure= the brass rod is well "centered" on the plate ,
Clamp "it" twixt the jaws of a 3" ++ C_clamp ... the fluxed braze will
'wick'
into the joint, at "heat" , in similar fashion to solder.
.. Do your best to 'center' the brass rod,
.. drill 'thru' the center of the brazed assembly ,
.. thus going 'thru' the center of the brass rod.
.........
I think the lever "below", is aligned to the center of the OEM TA,
and, ...
mite be about 1/8th inch in 'width' .
Your hacked 'piston' should aughta, pretty much ..
hit this lever, "center-on" .
Thus,
the need to assure a 'centered' drilling of the 'scratch-made' TA .
Worst thing you can 'do'
is rush ...
or,
be unwilling to bash it, yet again, a second time.
Got enuf 'milk' ... stock ???
