Okay guys first time poster, forgive me if this is common knowledge, I looked through the forums and couldn't find an answer. So I ordered this front end parts kit for my 2001 lexus es300. It has all the bells and whistles, but I find that two boltholes for the lower control arm are too big where the lower ball joint mounts? I thought this was a design flaw for these cheapo parts I ordered, but after looking farther I realize that all the lower control arms by different manufacturers have the same odd design. I need to know if this is normal or not before I grab my pitchfork and demand a refund! (Or put them on.) Maybe if I take one bolt off the car I would find they match the oem parts?

 

The factory nuts and bolts are tapered not sure why those came with generic type fasteners. I can't say if those parts will fit properly but you can't use the nuts/bolts they came with.

 

Those won't work very well. They need to be exact otherwise your ball joint location will be offset and your alignment will be screwed up.

What brand of parts are these and where did you get them from?

The OEM arm on my car shows a bolt that is almost the same diameter as the holes on the control arm:
