As the other Three posters noted just reverse the rails...
I use a Biesmeyer 50 inch fence and rails BUT I off set them 12
inches further to the left then normal...(the saw fits the shop
better)...and allows my jointer to sit next to the saw...

Any right to left tape measure will work...... I needed the standard
left to right tape but I needed the zero point 12 inches from where it
originally was... BIG deal...
