well i went and picked up the donor vehicle, and took all the damaged parts off i needed to so i could get at the engine and see if it had any visible damage, and the engine wasn't touched, other than a slightly bent oil cooler pipe that had touched one of the belts, but that was soon sorted, cutting the AC lines, was most shocked, the AC was still fully charged, so what a result, these engines and boxes are going for $10k on ebay, i only paid $3k for the complete truck,
