Barney,
Don't know the definitive answer but I bought two used "B" blowers at
the 2nd Annual swap meet here last Feb. You were there I think. Cleaned
them both up and mad one from the parts. Put it in the heater box for my
"A" roadster. Also included the plastic fan ass'y from the "B". Fits
very well in my "A" roadster heater box. Also looks just like the
coupe's fan.
You shouldn't have any problem.
