1969 C10 ECE drop spindle ball joint

[1LIME69]

Does anyone know what year ball joints are used for the ECE drop spindles with stock control arms? That is what I am running now, but I am looking at upgrading to the QA1 front coilover conversion kit. I remember installing new ball joints during the install but can't remember if I installed new stock ball joints or installed 73-87 ball joints.
Also, does anyone know if it is ok to use drop spindles with the QA1 coilover conversion kit or should I just use stock height?

Which kit did you buy ?
The made a 67 70 spindle kit used 67 70 stock tie rods and ball joints
They made a 71 72 kit using 71 72 ball joints and tie rods
They also had a 73 87 kit

That's my dilemma. I don't know what I have. Didn't realize there were so many options. Is there an easy way of determining what I have from a visual prospective?

Here is the Disc Swap fact there
you could measure your tie rods against it on the list
or take apart your ball joints take them to the parts store to check against new ones to match up
