Door lock/gearbox expert

Hello,
My back door gearbox is jamming.

The marking on the box is GU 35/92

Is it worth fitting a Yale Doormaster replacement at 55 squids.? from screwfix
Does anyone know if that is an uncomplicated direct swap.

Or, do I just get another GU35/92. 35 squids. ? this one lasted 17 years.

cheers
Howard

I used the Yale kit from screwfix a few years ago and all is well. I think I had to modify it a bit as it is a complete universal kit but seemed good value as it replaced everything.

is it the lock mechanism or sliding mechanism

if sliding mechanism your best getting both the lock and the slide

Thanks guys,
my concern is the compatability between the new yale gearbox and the existing slide
I don't want to be buying a complete kit.
So, I will go for the GU box, thanks
