I'm getting closer to the install phase of my 455 into my 4 X 4 Suburban. I will be having my BOP case T-400 rebuilt configured to bolt to my transfer case. I want to use a towing style converter if possible and bolt it to my existing 455 flex plate. I see that TCI, Hughes and B & M all make some version of the towing/RV unit that offers lower stall speed, etc. My question is whether or not anybody has experience with any of these style converters and will any of them line up and bolt to the Buick flex plate? Thanks guys!
