U-bolts for Lower Control Arm

[siggyfreud]

Anyone know where to buy these? Some threads on one of mine are stripped. Are they astonishingly easy to find and I'm just being an idiot?

I'd like to order these:
Amazon.com: Dorman - HELP 13503 Lower Control Arm...
But not sure if it's a one-size fits all thing or not. I search Google for 1985 C10 Lower Control Arm U-bolt and I just get a bunch of articles about installing LCAs. If I switch to shopping I get that one Dorman part number (13503).

If anyone has an easy find let me know.

Thanks all!
