what's being said trukolet, is that your claim that all TF frames were painted semi gloss black is without foundation, I haven't seen anyone claim the trucks were sent from the factory with "rusty frames", in fact if you review the thread above, I suggested the possibility that a phosphoric bath would serve the cosmetic purpose for sales .... you continue to assert that the few trucks you've seen, that you believe were original, are the way they all were/are, most folks here accept GM production documents as evidence of what was most common at most plants, not your anecdotal evidence
