Upper control arm washers
 

1982 ½ ton C10
I am upgrading my 70 c10 to power steering using a 1982 doner. Ran into a problem on my suspension rebuild, 2 leftover washers in my bucket (small ones in the pic).

I figured out where they go. 1 washer per upper control arm next to the rear bushing. Circled in red in the pic. The picture is a lot better on my computer, I can see them clearly. It bugs me I left them out, but they don’t appear to be needed. I can’t find them in the catalogs. I have not found a thread here of anybody using them in their rebuild, no you tube videos either. So……..can I leave them out?

I doubt there will be significant impact. I'd roll w/o them.
