Help finding 94 j30 part

[stoned99]

I recently took on the task of replacing the antenna mast in my sons car, and somehow managed to loose the base nut that holds the antenna base and mast in.

I've been very frustrated by the numerous nissan parts shops that all seem to get their stock from a central location that does not have the part available.

eBay has been a dud too, and nothing at my local wrecker yards

The part is 28219-0p000

Any ideas, advice, replacement, jury rig, options ?

Thanks

Anyone know of a car that shares the 16mm 1.0 pitch Base Nut
