Did you overpay? Maybe, but honestly that can happen with any impulse purchase of anything. You’re digging in and having fun.
Dig in, clean and fix it up as you go! If you have non-US specs, specifically Mideast, there are several folks here who are happy to help. My 40 came out of Saudi!
There are importers who do things right. Every truck I bring in has disk brake upgrades and full mechanical repair/restore done… bearings, bushings, seals, gaskets. We’ll rebuild an engine if the compression is poor. Some importers here bring them in as-is and are as honest as they can be about what it is. The same cautions that apply to buying sight-unseen on Craigslist from Arkansas apply to buying an imported truck.
