Ford c6-aod conversion

Well I ditched the c6 and have the aod in my monterey. Only issue is that the universal joints that work on the drive shaft are too long for the aod slip yolk. Is there an easy way to work around this? I thought about grinding a little bit off each end of the universal joint but wasn't sure if that was a safe idea.

Do not grind. speedway motors has conversion u-joints that will work

Look up drive shafts in your local yellow pages take the drive shaft and yoke with you,most stock conversion joints by NEAPCO.
