What do you mean?
How to bolt the softtop frame into the compartment?
There are two main mounting brackets with hold the main hinges, one left and one on the right side.
You just bolt them in into the softtop compartment's bottom. There are cage nuts already in place.
Pretty easy and forwarding. The adjustment to the side windows is another story.
Don't forget the shims underneath.
Do these pics help?
The last one shows the letside mounting bracket best. It's from a 280ies softtop; thus, a bit different than yours from a 230.
Good luck,
Achim
