I am a little slow getting going here. Seems several places make the engine mounts. Looking to retain the factory A/C so I am checking into that. One thing I haven't been able to find much information on is the transmission. Aas seen in the above pics it's the 3 piece 4l60E. Can I just switch the bellhousing over to the "LS" style or do I still need some kind of adaptor? I've read varying opinions on this. Some say input shafts are different and torque convertor spacing is different, etc. Anyone here done this yet?
