I just pulled a 04 Durango 5.7/545RFE, I will be stabbing it into my 79 w100 stepside. I noticed the 545RFE bell has provisions for starters on either side. The trucks used the drivers side and the durango uses the passenger side. The other hemi I pulled is from an 03 ram 2500. The 545 is a heavy trans it's almost 100 lbs more than the NAG, the ratios are also much wider than what you want for a car thou. The 545 has a one piece case as well.
