I don't know anything about the Bajaj front end. I think the problem may be with the mudguard. Have you thought about putting a spacer on the fork mount before you put the mudguard on, the only problem with this will be the two bolts on the side of the mudguard will not line up.

There's no real room to space the mudguard up higher, without it touching the frame maybe 5mm - 10mm, not enough to help.

I've sourced some Bajaj 10" forks, which have the same tube length as the VNB, same steering lock etc, the stem is 20mm longer, so I have spend all day swapping over the hub, links, shock. Realising it will need a longer spring than the 155mm 8" spring, I had a 180mm spring that I shortened to 165mm, I had to overcome the mudguard fouling on the frame, but the diving was even worse than with the 8" forks, where do I go from here? (Is it down to the lake I fear).

I think the best way forward would be, buy a new spring and bgm shock. but they do tend to dive. i generally only use my front brake at the end of braking. if its cured the rubbing thats a good start.
