Flaming River coupler installation (Problem solved)

I bought a Flaming River universal joint style couple for my 68 Barracuda. The instructions PLAINLY tell you that you need to cut 1-1/2" from the shaft. Which I did while the car was apart so I could be very careful and cut EXACTLY 1-1/2" from the shaft. This is a manual steering column and the FR1506M coupler. I went to put it all together and it's 1-1/2" TOO SHORT!!! I'm totally screwed. I will be on the phone with Flaming River Tuesday hoping they can Help me find a solution.

This is a 68 auto on the column with the reverse light switch at the base. Any one have one for sale???
