Volvo was not helpful at all, when I was searching for parts. "Not in stock, and will not be in stock..." Is what they said. Also searched eBay, but without success
So a family member, who is a retired Bosch diesel technician. He knew where to get the few parts i needed for my coldstart-project. It was probably direcly from Bosch. The only thing he needed to know, was the Bosch part number on the IP.
When assembling, I did exactly the same as you, V8Volvo. I began with some longer screws, and when the regular ones could reach, I continued with those
