Front UCA R/R and alignment question

[HISSIN50]

Hello,

Just a quick question for the folks that have R/R'd the front UCA's. In reading a lot of old threads, it sounds like the alignment can be off after doing so. Just so I know ahead of time, where does the change come from? I'm assuming the holes that the two UCA-to-frame studs go through must be bigger than the bolts themselves, and thus allow some change in alignment. If so, are there any tips/tricks to mark or index things so they go right back where they came from?

Otherwise, if those holes are only as big as the studs, other than forgetting shim orientation, where would an inadvertent alignment change come from?

Thank you guys!

As long as you re-use the shims and installed what it was before, there should be no problems with the alignment. I used mevotech to replace the OEM upper control arms and has no issues with alignment. The bolts are exactly the same size.
