Convertible Top Restoration. Need a good shop in SOCAL area.
Eric Thorson is really top notch but he's not going to be cheap.
http://www.thorsencustom.com/ And he's in Agoura. Not too far from you. He does a lot of Steve Strope's Pure Vision stuff. Tell him Steve from Justice Brothers sent you.
I'd think there would be someone good in the Ventura/Oxnard area closer to you. I'm just not that up on that area.
There's Jessie's Upholstery Saticoy: 11019 Jacinto Way, Ventura - (805) 647-4580 I just drive by there sometimes. But I have no direct references to their work.
