Glad it worked out for you jorge...
Were you able to find some used ones or some other aftermarket...
FA is a PITA with their grips... I had a 6" .454 back around 2000 that had the the black Micarta grips. I was going to trade guns with a friend who had ended up with two 4.75" guns but I wanted to keep my grips...they would not interchange on either gun...so I ended up selling mine when the .454 rounds just started causing too much discomfort to shoot...found an identical one in .41 Magnum and have lived happily ever after...
