Not next door to Ventura, but check out "Affordable Classics" on Hawthorne Blvd just South of 190th Street in Torrance CA! They have a good reputation and make a good living restoring classic vehicles, and I have seen some Japanese clasics in front of their shop. There are many other specialty shops in the same location. I had a new down pipe fabricated for my RL411 in that complex. It's not a common or readily substituted item.
