Tom, don't forget, a bad drive line vibration and "play" can also attribute from the aqs engine oil pan, worn iso mounts, worn engine cradle, and perhaps the engine drive hub and bushing.
None of these repairs are difficult, just taking time to do them usually results in a good correction made. Could be that the 1450 was operated quite a lot while being bent, or leaning, causing a drive line aggravation.
