I have a 1923 touring , does anyone know of a resource that will rebuild the differential for me in the San Diego or Los Angeles area - its got a pretty bad leak and I am sure needs a full rebuild
A lot of the guys in your local club have done this. I bet some of them would be glad to help you fix it. I hope one or two of them will see this and contact you. All the new parts you might need are in Corona.
Contact Larry Blair at the Tin Shed if you want someone who can do the work for you.
Take it to Larry at the Tin Shed. You won't be disappointed!
