can someone tell me for sure if these would fit

[71Chevystepside]

Here is my problem,

Started working on my 71 C10 2wd stepside project again and took my front upper and lower control arms apart to paint and start reasemble.

I found my lower arms are both smashed or dented on the front where the shaft assembly mounts, I would like to change them out with non bent arms.

I have a 72 C20 2wd out in the weeds that should be great shape, but before I get real dirty in the mud and weeds,

??? would the lower control arms from the C20 work on my C10, I know the ball joints are different but are the ball joints holes the same diameter (I have new C10 ball joints ready to install, again would this swap work,

Thanks in advance,
Rich
