Looking for a 70 series owner who previously owned my 40?

[BigBird77]

Hi looking for a previous owner of my yellow 1977 FJ40 that has a 3B and H55F from a Canadian BJ60. I bought it from a consignment dealer in Concord, CA in July 2018. The dealer said the owner lived near by and had a 70 series. Possibly Walnut Creek or Lafayette? I am asking because it has a pretty new Garrett turbo that was added by the PO and it needs rebuilding. I am curious if they have any of the warranty info or paperwork that came with it.

Here’s a photo of what it looked like when I purchased it.

Thanks for the help!
