need to use a drivers door latch grab handle, t6.1 latch width dimensions?

[whatsisname]

hi all,

I am looking at a few t6.1 this week. I will need to use a grab handle that slots into the drivers door latch to get in and out. would some kind soul measure the inner width of the door latch please? I have several of the grab handles, and when turning up for a vivaro test drive today, all were too wide to fit in the door latch. want to turn up for the t6.1 inspections and test drives prepared.

thanks!
