Star Trek TNG catapult ramp alignment & identifying hex post

[jwsmith]

I have a Star Trek TNG where the catapult ramp seems to be misaligned such that the ball is bouncing into the playfield and then either fouling or getting stuck against the top right jet bumper, rather than going up to the 'advance in rank' lane lights and 1-Bank drop target.
On inspection I saw that the hex post next to the Delta quadrant ramp had sheared off at the base (images below) and I'm assuming that this effectively anchors the crossover ramp to the playfield, which in turn is attached to the catapult ramp and the force of the ball going round the loop is causing it bounce off and not enter the playfield cleanly.
Does that sound correct and the likely issue, and if I replace the hex post then can use the two adjustment points on the loop ramp then I'll be able to get it properly aligned again?

If so then can anyone confirm whether the correct part if #02-4934 (ramp post)? The piece is 8mm wide and 58mm long hex shaft with a 5mm thread on the end.
If that's correct then I've only been able to find it at this site in the US - is there any equivalent piece that can be used and sourced in the UK/EU?
This from Best of Pinball in Germany looks very similar other than the long thread, but is listed as #02-4935, which I don't see referenced in the manual...

Thanks for your help!
Disclaimer: I'm a relatively new pinball owner (6 months) and aware the ST:TNG is considered one that requires more maintenance and so not too experienced but keen to learn.

Bit confused - is there anything wrong with the hex post? Do you just need a new screw and washer to attach the habitrail to the top of the hex post?

Sorry, I should have been clearer, I have the screw and washer for the top but just hadn't screwed it back in when showing the post in its position in the first image.
The thread has come out of the bottom of the post, as shown in the second image; I assume it can't be secured back in there in a way that wouldn't quickly fail again once the force of the ball around the loop is applied a few times.

Okay, got it now. Yes you’ll need the new post - ordering from Marco isn’t too painful if you have any other parts to order from them at the same time. If you’re lucky somebody else on the forum might have one. Just make sure you don’t over-tighten the new one!

P.S. I think it’s supposed to be a thicker yellow post rubber on the lower entrance post of the side ramp (E on the diagram) - looks like you have a black one on there now
