Valley Hybrid in Stockton, CA is the ideal shop to maintain and work on diesel Landcruisers. We have a 60 series, 2 40 series and an 80 series that they were involved in converting to diesel and currently on a 70 series. I've worked with them for the last 15 years and can not say enough good things about them. Georg @orangefj45 who runs the shop is my guru.If you are in LA, you have K&H Imports locally. They worked on my 70 series (diesel) when I had it imported. They might be an option if you really want a diesel but finding a local shop is stopping you.
