"Converter change" how much improvement...

I ordered it.

I have the small u joints, i'll be installing the "brute force" joints shortly, also going to install SFCs @ a loop.

The bell houseing bolts are stock, i've never had issues in this area, i do still have the factory torque bars from the 318 that connected from the trans too the engine, but i don't know yet if they will fit the Magnum block.

torque bars I never run.

my point was you wouldn't have broken the convertor bolt, no big. enjoy!
