Hellcat Swap Into 72 Demon
Here is a third bellhousing option. Not saying it is better, just an option.
Pretty sure this is the one coming with my SST kit.
Quick Draw Mopar Hemi to Tremec Magnum T56 Bellhousing - Three Pedals
BTW, not doing the TR6060 swap now. Wasn’t a lot more for a new T56 Magnum with the current deals and if the used TR6060 turns out to need parts pretty sure it would cost more in the end than just buying the kit.
