jackson king v std professional nut

[superev1l]

I picked up a jackson king v professional std (not the neck through ebony with binding)
The nut is worn. I have an r4 and r3 here and those seem to have the right spacing but are WAY taller than the stock jackson nut.
From some research im thinking it is a bh-43 but the nut on my king v is not stamped so i cant be sure.
Does anyone know for sure wich nut it is? Guitar is from the 90's

Update,its not a bh43. it measures the same width.The hi and low e slots are even but the string spacing in between is way different,and the saddle height on the high e string is .200 instead of the .225 on the bh43
