727 slip yoke or shaft

Guys

Changing from 904 to 727 in the wife's 71 swinger and need to have my driveshaft shortened and install a 727 slip yoke.

Before you ask why, I need the 904 rebuilt and the 727 is ready to go in the garage.

So, I'm looking for s slip yoke, possibly and entire shaft with the yoke, or maybe even an already shortened shaft.

Pm me with shipping and price to 43031.

Thanks
