I cant find anywhere to get a quote from
Petes' gear works in Hayward. Some other places will build them as well. You can look in the yellow pages under automotive differential service even some transmission shops will build rear ends. The reason I ask is since I've always built my own I might be able to save you some money and be fair with the build cost. I just don't know what they are charging for a gear build these days. I do have all the proper tools and have built many succesfully. I'm in Dublin also.
