Your camera has 395mm max extension while this lens requires 284.9mm to focus infinite, so you should be able to focus closer than 2m (1.2m perhaps), if I calculated it right (
https://www.kennethleegallery.com/html/tech/bellows.php) so you don't need much the extension board for this lens, but I don't know if your bellows are too stretched at max extension, which can provocate internal reflexions ending on the film sheet, so IMO what you should check is if your bellows are long enough, as said, this can also be overcomed with a compendium shade to trim the excessive circle.
The nikkor 360 I shot with is the W 360, mainly for 8x10, and also the W 210 that nearly covers 8x10 and can be it used for that, both are superb. Anyway it's dificult to find a modern LF plasmat lens that is not delivering a crazy good yield. John Sexton exceptional master made most of his work with those Nikkors, still he owned several units of the same model to get top perfomers as there is some variability from sample to sample, for sure me and many would not absolutely notice any flaw in the glasses he replaced, but that variability existed in the production of all manufacturers.
