How low can a Tie Bar go?

[Phil GTE]

Hello.

Part of my Nova rebuild includes lowering the tie bar brackets.
As we know, to do some envolves filing the single upwards. See picture, the original hole is marked by the red circle. Having enlarged the hole, I need to know how far I can take it - see the green box.

Therefore the question is;

How much lip should there be (safely) above the bolt hole?

Realise I will need a spacer machined - not an issue.

Thanks everyone.

you can chop the top off and weld on a longer piece to drop it 25mm...

I have never seen the top hole being inlarged, I have only ever seen the other top part being welded on the top!! I would do that mate.
