extended front wheel studs, '00 Tacoma 4X

So I installed some new, longer front hub studs today .
they were a little longer then what I hoped
could be slightly shorter... but they'll work.

http://www.wheeladapter.com/wheel_studs.php

my measurement of these lexus IS300/toyota extended studs are:

M12 X 1.50, 52.5 mm actual thread length,
14.20 knurl diameter, 7.5 knurl length
total length 63.5 to seat - 68.5 over-all )
( there is a 3-4 mm shoulder between the threads and knurl )

measurement error +/- .5 mm

I had to bend (hammer) the backing plate
in a specific location, in order to insert the longer studs.
they just barely clear, but do

pics because...

backing plate bend location...



hammer time...



stud removed...



new stud being inserted...





how I pulled the studs thru...



studs installed...





this stuff helps slide that knurl home...



wheel reinstalled...
there are .25" spacers installed...
just not the billet ones I purchased.
farked that order up because I didn't pay attention,
and failed to account for the correct center bore diameter.
so I'll need to have muh billet spacer's machined out if I keep 'dem.

btw... these are open end ET 6 spline drive lug nuts
just so it's understood, there's a shit ton of thread bite







^ I've since painted the stud thread tips black
looks less obtrusive IMO... maybe a pic of that tomorrow (IAGAS) :dunno:

-----------------------------

few questions... if ya have the know

my front factory studs were only 30 mm long,
was thinking they were 40 mm. sooo...

1. what is the actual length of the rear studs ? 40 mm ?

2. do the factory Rr. studs have a shank at their base ? how long ?

3. what is the tacoma's front hub diameter ? 97.1 ? More ?

google search brought up too many answers
and they were inconsistent and possibly not reliable.
I could pull one and measure...
but was hoping to know, without doing that.

^ I'm asking specific to the 1st gen, early to mid
as they may be different on the later '01 - '04 tacoma

clarification would be appreciated

--------------------------

here's some other misc. pics...







pics of the "no bueno" billet spacers

 

had someone local, lathe the spacer's center bore out for $20.
they fit great now... stronger then the universal cast spacers.
Slightly thicker too... billet = 6.2 mm Vs. cast = 5 mm







also painted the stud's thread tips ( outboard of the lug nut )
just thought it would look cleaner this way...
^ tho' "good looks' isn't my primary concern

here's those...

Nice! That would have been perfect. Unfortunately I was in a hurry when I put up the post and didn't have to much time to wait. So I went for it and after a nightmare of a time trying to set the lug stud, I got it. Thanks
