Under dash clutch pedal assy.

[54belair]

Im changing over from auto to manual, I got one clutch pedal assy with the parts stash when I bought the truck, plus I bought another one (to get the springs etc.)
My question is this--There is a difference in the assys, one has a large spring tower on the top of it while the other one does not have this "tower".
So, my question is---whats the difference in applications? which is the right one for a 68?

I have the factoy assembly manual, with the thousand or so diagrams. In the manual--(about 25% of the way from the front--since there are no page number or ref. numbers in the book), anyway there are two pages showing the two diff. brackets, there are some number which Im sure refer somehow to model number of the trucks---but I havent ben able to decipher which I should use.

Now to my second question-----does anyone have pics showing their pedal assys? or would anyone kow how to tell me to decipher "the code" in the book??

I just looked at the assembly book again---One pedal assy is referenced as CA100-200-300, the other assy is referenced as a CA400-500-600. still havent figured out the difference i numbers.

CA100-200-300, refers to 2wd 1/2, 3/4, 1 ton and the CA400-500-600 is 1 1/2 to 2 1/2 ton models

Yeah, thanks for the pics--- Ive done more searching over the evening and it does appear that the 100-200-300-400-etc designation does relate to 1/2 ton, 3/4 ton etc.
Evidently the one for the bigger trucks has a heavier return spring located on the side of the pedal--not on the top like yours (and one of mine). There is a difference in the location of the "tower" for the upper spring attachment.
I bought the second one to have springs and such that the first one didnt have----but, they wont interchange.
But,, Im now sure which assembly I want to use!! I was able to find the springs and parts I do need at LMC----so, all is good----thanks guys,,,

Tim,
That's a nice write up... should be in the FAQ area if it isn't already

Here's a couple of pictures of mine, in a 1972 K-20: (sorry for the graininess, but they're from my cell phone)

Ok, you have "side spring" style---this is the style that I thought was for the bigger trucks!! Must be some other deciding factor on which assy you have (Im back to guessing its something to do with the year??
