Larry,
There is no question that I am not a guru on C3's. The information I posted was taken from the 1969 AIM. I won't be where the AIM is located for a few days in order to scan and present the page number.
In the meantime I followed your suggestion and read through the forum archives. Perhaps the following thread can provide more insight into the use of cotter pins in the trailing arms.

Among others, these people mention the '69 AIM showed cotter pins in the above thread.

An addendum to my post above.
Attached are photos from the '69 AIM UPC 4 B3. Notice the cotter pins were a revision during '69 production.

The AIM showed the change during '69, but it wasn't actually implemented in production on cars (slotted shims and long cotter pins) until late 1970 - early 1971.

When reading this thread i come to think of my own car.
The first thing i did was to change the rear spring and the spring i recived was a "heavy duty" spring.
I suppose that is a 9 leaf spring?(the car is in winter storage)

The standard spring had 9 leaves (3 flat leaves on top, 6 curved leaves below the flat ones).

Hey John - that's what mine looks like now! Hope to finish tomorrow night or Saturday - just have to put the TA shims in, button up the exhaust and install the valance and spare tire tub. Hope to post some pics of the end result.
Thanks again all.
Tim
p.s. - the "heavy duty" suspension spring was actually 7 leaves

just about done
Just about done with my spring project - all that's left is to button up the exhaust, rear valance and spare tire tub - anything look out of order? - keep in mind, this is not an NCRS car
Thanks for all your help,
Tim

Looks great to me! The curved/dished washers on the lower shock mounts should face the other way - large ends facing inboard.

John - you mean these?
they are listed as a "retainer" in the AIM - they are cupped I assumed to mate with the lower shock bushing - these should be turned around?

Thanks John. That's why I posted the pics - the AIM is not detailed enough and I made the assumption that they cupped the bushing underneath.
Will change them tomorrow.

Will change them tomorrow.

BTW - the "stance" on the car is much improved over the way it sat in my avatar. Although I understand it will settle a bit in the coming months - but still a huge improvement.

Put a floor jack on top of the differential crossmember and wrap a chain or tie-down strap around the spring and jack lift pad, and pump the jack. Use a C-clamp on the spring so the chain or strap can't shift inboard while you're compressing it.

Put the chain around the spring as close to the outside bolt hole as you can. Loop it up around the crossmember on both sides and over your jack pad. Complete one side at a time. Put the clamp inboard on the spring next to the chain to prevent the chain from slipping up the spring arch toward the differential. Dave
