Rear UCA bolt too big for spindle

[dr-sicel]

Really bizarre -
I’m assembling the rear suspension - and it appears the 4.25” (5/8”) fits the alignment spacers nicely but is substantially greater in diameter than the hole in the spindle.

I’m assembling the MKV w/the spindles included in the kit.

There are no other bolts of that length in the IRS fastener kit and it would be odd to have a smaller bolt as the other parts clearly match the 5/8”.

Thoughts??

Thanks! (I didn’t find any other threads for this on the search (such as it is), which surprised me)
