Not really sure when this conversion was done as the guy I bought it from also purchased it this way and he had it for about 9 years. I have owned it for another 3 1/2 years and upon a closer inspection conducted this morning with a good eye and a flashlight of the bell housing there is no outward appearance of any cracks or damage. Of course I did not tear it down so there could be cracks or damage not seen by the naked eye. I have combed this forum and it seems a lot of Bolters are asking this same question regarding this conversion. I am going to look around and see if there is a mount that can be attached to the frame to shore up this middle area where engine meets transmission. Thanks HUGH
