There  is  NO  1  Needle assembly  that will  fit  all those  engines, you will  need  different sizes

Randy

      Yes Randy, I am aware of the this.  What I was asking is what are the part numbers of the Enya nva that would fit each individual engine.

     Be well,

Sorry I do not have  part numbers   for you,  but, There is not one that  fits the  FOX 35,  Shtterman  on Ebay  has a  special made one  that  fits  the  OS 25 and 46 LA, also the  FP 35 and 40, it is a  smaller diameter NVA.  NOT one that fits the  HP unless you modify it, however  MECOA  has  stock  HP  NVAs  ,  and  you can use  one of the  mid size  Enya  NVA   IF    , you drill the  front housing  thru, and  mill  or  file  the  edges  flat.
The  Brodak 25  many use a  ST  or  PA  nva,  and you  can measure  the  width, of it, then  use the  Enya  mid size  NVA  that would  work for that  spread, maybe a  SS40  NVA, you can do the  same for the  HP  if, your  using  a restrictor that goes thru the  front housing

     Hello Randy:

     Thanks for the help.

     When I started this quest for nva, I was overwhelmed with all of the many various sizes that were required. Lol. The most annoying feature was the many widths required.  Oh yes, thanks to #8 nylon washers, many nva. can be made to fit.

     In any case, this search will keep me out of the bars. Lol

      Be well,

Nylon washers  are the  worst  thing  you can use, they WILL  CRUSH and they will then get loose  and  leak, The  hard red fiber  washers  are better, but  they will  do the  same thing after a while, best bet  if you do this  is to  make  aluminum  washers out of  soft aluminum, they will be  the only thing  that really works !
Also the span  is not  the only thing you need  to vary, many of these  motor  have to have  different  diameter  Needle assemblies
