A100 Idler Arm

I didn't remember mine having a idler arm but I forget a lot anyway.
That looks just like my 63 Econoline steering. No Idler arm either.

As for left side tie rod end measure up the right side and start digging at the parts store. I bet there is a tie rod end that will work might not be perfect but will work.

Also if your not trying to do an OE restore you could use two right ends and make a new tie rod with the same threads on each end, pain in the but to adjust but it would work.
