[DeTomaso] Is this a workable pedal pivots upgrade??

[jderyke at aol.com]

Larry, in my opinion any retaining pin hole will be outside the loaded area- thus not a problem. The only difficulty will be in drilling a hole thru what should be a hardened pin. This requires a carbide drill and they are brittle so not easy to hand drill without breakage. On our car I found every single pivot pin that was NOT hardened, was worn part way through.
Cheers- J DeRyke

All,

The accelerator, brake and clutch pedals all pivot on pins that use either E-clips, or C-clips. 

They are a royal PITA whenever you must deal with them. 

There is another option often used to retain pieces to a shaft, the hitch/hairpin cotter pin:


These pins are much easier to use than the stock clips. They do require a drilled hole through the shaft. 

With my pedal box sitting on my workbench it looks like the accelerator shaft has enough meat to allow the drilling of a suitable hitch pin hole. Or, as it is pressed into the housing, I imagine it could be pressed back out a little bit to provide a better drilling position. (Obviously, to drill a pin hole while this shaft is in the car is likely an impossible task.)



But for the clutch and brake push-rod pivot shafts, a longer clevis pin looks to be a workable conversion:


McMaster Carr stocks the sizes that would be needed:



Do the engineers on the list know of any cautions that would deter the use of these clevis pins/hitch pins in our Panteras?
