I had good luck with Mike's Auto Tops & Upholstery in Mission Viejo. 2 to 3 man shop, 25701 Taladro Cir Unit D Mission Viejo, CA 92691 United States
I've used Bill Dunn in Huntington Beach. Hector does great work. Pm me if you want an introduction. Andy
Does he do a lot of Harley Davidson work? If so, I think this is who I used about 10 years ago to do the seats on my 308 GT4. They did a great job on my seats.
I don't know about Harley's but the few times I was there, they had a Testarosa undergoing a full interior restoration and a Alpha 164 getting a similar treatment. I had him do some customization on my Mclaren floor mats and add an Alcantara headliner, a-pillar and sun visors to my Porsche, both projects came out very well. MB
