<p class="MsoNormal"><span style="font-size:11.0pt">Are we talking the camber compensator for the Spitfire that has a middle mounting bolted to the bottom three bolts of the differential?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The scariest moment I ever had in my 1964 Spitfire, back when it was my daily driver (ca. 1967), was when my diff locked up as I was passing a semi on I-35 in Kansas City. I barely got the car over to the
shoulder without getting run over, then spent six hours on the roadside waiting for AAA to send me a tow truck! (That’s when I decided not to renew my AAA membership, but I digress).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Turned out the middle mounting on that camber compensator had broken off the sections on the two end bolts because of the constant flexing on it, so only the middle bolt was holding it in place. The constant
action on that one bolt eventually made the round bolt hole oval shaped, and all the diff fluid drained out. A dry diff really doesn’t work all that well.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I drove the car without a CC for a few years, then gave it to my brother (who’s a mechanic) to turn into a race car, He came up with a solution which I understand originated with Volkswagen owners to address
the Beetle’s swing-axle issues. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">He tied a cable to the bottom shock mount, ran it up to a pulley attached to the top shock mount, then across to the same setup on the other side.<o:p></o:p></span></p>
<p class="MsoNormal"><img width="218" height="178" style="width:2.2708in;height:1.8541in" id="Picture_x0020_1" src="cid:image001.jpg@01DB99A4.03781810" alt="A diagram of a shock bolt
AI-generated content may be incorrect."><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The biggest modification was to take that big bolt at the top of the shock, drill and tap it through the head to take a shouldered 1/4-inch bolt which becomes the hub for the pulley. Not shown, a simple retainer
over the top of the pulley to prevent the cable from jumping off. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">He did that in 1971. He raced the car for three years, then I got it back and raced and autocrossed it through 2011. In all that time, 40 years, I replaced the cable just once.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Since it was going on a race car, we jacked the rear suspension as high as we could (filled the trunk with heavy stuff while the car was on jackstands, then sat someone in the trunk while we attached the cable)
which both lowered the car and stiffened the ride. I later bought another ’64 Spit as a street car and did the same trick, but let the suspension droop more so it was softer for street use (I also didn’t autocross that car). On that one I found a pulley that
came with a shroud, didn’t need the retainer.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">It works as a camber compensator without that evil spring. The swing axle doesn’t swing any more. Both rear wheels remain constant with each other.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I’ve given this design to several other drivers. One came up with a clever trick – he cut an opening in the diff tunnel under the gas tank (which also provides nice access to the bolts holding the spring to
the top of the diff). Then he installed a turnbuckle in the cable at that location. Adjustable suspension! Cheap and easy. And IMHO safer.<o:p></o:p></span></p>
