Z4 Roadster Hardtop Install (MISSING REAR LOCKS)

Wanted to make a short writeup on my hardtop install, nothing too special however I did have to make my own brackets to hold the rear of the hardtop down. When I bought the hardtop the seller decided to throw away the old rear locks due to them being bent..

Turns out the locks are near impossible to find and I had already ordered the "prep kit" for the hardtop so decided to get crafty until I magically find the rear locks for it in stock somewhere..
Rear lock part numbers are : "54 21 7 076 357" and "54 21 7 076 358"

Heres some pics, it has held up to some pretty aggressive mountain and backroad driving, I don't doubt it's on there however I don't necessarily have a way to cut on the rear defrost...
All I used was home depot hardware, and put a bolt, washer through the prep kit back out to a washer and nut, then it extends long enough to grab a little bracket made sandwiched in the hardtops hardware, which has a nut ontop to hold it all down. I have not tested to see wether the soft top will come back up yet - I will shortly and update this, the idea was to remove the hardtop and let the super long bolt drop as far down into the prep kits hole/post whilst the nut stays ontop to prevent it from falling all the way through..
