R27 Output Flange Interchangeability

Anyone know if a /2 output flange can be used on an R27 transmission?

Renner,
If the taper and thread is the same it looks like I could get away with cutting off the end of the R27 shaft? Thanks for the pictures.

It sure looks that way.
Unfortunately I don't have a spare R27 output shaft for hands-on comparison.

The keyway is also different, as you see.

I'll have the motor and trans here later this week for a special build. I'll check it out.
Thanks again for your help.

It may fit on the taper but the R27 arrangement is quite different with two "drive pegs" coming off the flange into a rubber donut. The flange on the driveshaft also has two pegs which also go into the donut. Cush drive!

This is why I would like to go to the /2 style so I can run a u-joint style driveshaft with this project.
