The Richmond is very easy to work on so whether you do it or you have somebody do it for you it's not rocket science. Just lay it on it's side and pry the two halves apart. Lift out the gear shafts and strip off the injured pieces. You will need some big snap ring pliers to get the retaining clips off the gear shafts and a tube of silicone to put it back together. Doug Nash used to include a "how to do it" service manual with every transmission. If you're lucky, Richmond may have their own version that they can send you that shows all the steps. I had mine apart three or four times to replace the synchros, etc. Check your linkage first though before tearing stuff apart.
