Sugihara Light bar on Stihl 036 - 2 part numbers?

[Evanrude]

I've received two part numbers for an 18" Sugihara Light bar for a 3003 mount Stihl. They are; SV3U-0Q45HV and ST2U-0Q45HV. Supposedly both are 18" 3/8 0.050" bars. So which is the correct one? I had a 20" Sugi bar at one point but it didn't fit the standard drive count that Stihl uses. Is one of these a better fit for 66DL?

ST2U is .325 .050. The first one listed is the 3/8 .050.

Dan is write. I have the SV3U on my 361. A new 66 dl chain barely fits with an 8 pin rim sprocket. 7 should be easy.
