All V89s in the little white book are 65 Barracuda's. There are no BP29s for 65 plymouth.

Got it. That is the only thing that I think might be an error that I have found on the earlycuda.org site. This is from the site.

“BDY” is the body style or model of the car
CH42 New Yorker
BP29 Barracuda
DL27 Polara
PP23 Sport Fury
etc.
