Bulkhead bolt to bolt measurement

Hi, I'm working on my bulkhead at the moment and want to check the footwells haven't moved. It was rotten when I took it off and I'm unsure if its moved whilst welding, can any off the experienced out there help out with the distance between the outrigger bolt holes please. Its a1991 200tdi.

Just had a go, chassis leg to chassis leg (outsides) is785mm, chassis leg to centre of bulkhead bolt is 360mm x2. A grand total of 1505mm. My B/H hasn't been heavily welded or galved but I have replaced my outriggers. Bolts went in with what is describe as 'a good tap with a medium sized hammer'.
