Borg Warner or Muncie?

[tsarbar]

I'm trying to determine the correct trans for a 2/18/63 build date, 340 horse convertible with a 90XX vin. My only source is noland's guide book, which tells me that no muncie M20's were installed before #14xxx (p190), How can I be sure this car was equipped with a B.W.?

Any other opinions?
Thanks Chris

The new 5th Edition NCRS '63-'64 JG provides guidance that the Muncie replaced the T-10 at approximately #15,000.
