PPF - Diff Top mount won't seat

Hi there everyone.

Doing a DIY clutch replacement on my NB and I’m on the home stretch. New clutch in and gearbox back on. I’m now reinstalling the PPF.

I haven’t fully removed it, I’ve left the last bolt at the diff end in (loosely) so that I could swing it out of the way. I’ve got all the gearbox bolts back on loosely and all I need to do now is get the frontmost diff bolt back in before doing an alignment. When I removed it, I tapped the bolt upwards to remove the top cap insert and allow the PPF to move more freely. Now that I’m coming to reinstall it, I cant get it seated again. I’ve tried threading in the bolt and pulling it down, twisting to try and get the splines (for want of a better word) to engage and just pressing it in from the top to no avail.

Am I missing something blindingly obvious?

Cheers.

Have you tried tightening the bolt to pull the mount down?

Yes, tried tightening till it was tight and no movement :frowning:
