upper control arms

So I’m trying to find the parts I need for mid to long travel front suspension. However, I’m finding that every kit or parts list with pictures that I can find in whole of the interwebs doesn’t look the same lol. The coilspring is literally through the freaking frame. How tf do I upgrade that...

recently i noticed that i had two different upper control arms on my 2000 4x4 and was wondering if that was something that was normal? if so why would they be different? heres the other side
