Tis a small world afterall. I bought a 1986 AA truck 2 weeks ago from a couple in Ft Worth and am rebuilding it to use in Dallas.
Do you by chance have a schematic of what 'should' be on the truck? and where everything should be ? Or wiring diagrams? The people before me did a lot of fixes themselves, and it's a mess. My spanish isn't very good, so I didn't quite catch what they were saying when they gave me the tour. Luckily I own a lube shop and car wash, so I have auto mechanics on staff. So far we have learned that the engine was actually out of 1978 truck.
Are you ever in Dallas, would love to have you walk through and point things out. I have a friend with a new gourmet truck, but aren't any help because theirs is all new equipment.
