I got a replacement part for an old door. I contacted the staff and they helped me pick the correct product using photographs I sent them. The part arrived but the door latch was slightly different to mine. I was sent a free door latch after contacting Dave who talked me through the install. 10/10 customer service!

Fitted this into my door and all seemed ok but when the original extensions were added the shootbolts stuck out slightly in the opened position and the roller's were fouling the keep, To fix the problem I had to cut about 10mm off of the top extension and pull it down and then move the bottom extension down leaving a 10mm gap in the face plate. I then had to move all the keeps to match in order to get the lock working again. A bit of extra work than I anticipated especially when it's advertised as a direct replacement but it is in and it does the job

The only way to save replacing the whole mech, similar cost, but a lot less work and fuss.
