Liberty gearbox circa mid 70's??

[Day2_69Z]

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: rafbody</div><div class="ubbcode-body">My father raced gas class in the early 70's and ran a super T10 with what my father referred to as liberty pro gears and an M21 with Liberty pro gears. He sent the M21 gears to liberty where they modified the stock gears and sent them back (my understanding from what he told me). I still have the M21 but took it apart a few years ago to get rid of the
liberty gears.</div></div>

In a scenario like you described it sounds like the Hubs (Sliders) were modified, not the gears themselves.
Every other hub tooth was machined off, and the brass rings removed, some had there gears &quot;hardened&quot; but those the 'first attempts' for durability. Until the High Nickel Clusters &amp; gear sets were developed.
The early 70's did bring in Liberty &amp; Doug Nash Custom High Nickel gear sets (Manufactured for those particular companies by another Gear Company)

Actually both the sliders and gears were modified. There were some sliders that had every other tooth machined and others that had the &quot;front&quot; part of 2 teeth machined with the Back&quot; half remaining and every third tooth was untouched. The gears were machined and the teeth that meshed with the sliders were modified.
