Tranny Questions

Tincup. Thanks for your 2 cents. What does that 545 come out of? I just decided in this moment that the guy who has the NAG1 from my hemi can shove the tranny up his a$$. i didnt have room for it on Saturday so I asked him if i could come pick it up today and he decided the price was double. Well hope he enjoys his yard ornament!
Would i use the OEM Hemi flex plate and converter for that 545 or do i need the converter for the 545?
