Flywheel Issues? I have an '03 4.8L engine to put in my Chevelle with a 700r4. I found on this web site somewhere that the flexplate to use is GM part# 12551367. The truck flexplate that is currently on the engine has an offset that will be closer to the converter than the conversion flexplate is FLAT. Any thoughts or insight on this issue would be helpful.

Well the truck flexplate that is on the engine is about 3/8 inch further from the block than the one I got for Chrismas. I am putting my 700r4 behind the 4.8 so I hope it all fits ok.
