hello guys and girls

i have a question i am hopeful to find a 292 inline 6 for my 38 truck but i was wondering what gearbox i would have to run as i am using a torque tube still and don't really want to change it.

the torque tube is out of a 37 sedan as is the gearbox i have currently if that helps.

any hints or tips or what i would need to do.

sorry if my question in kind of stupid still learning.

thank you all in advance

jeff
