Difference in 3 speed manual transmissions Truck/car ?????

What is the difference in 3 speed manual transmissions Truck and car ?

Found close to me a low mileage slant six from a 68 truck with a 3 speed manual.

I have a 66 valiant that is a slant/ auto I would like as a manual. I have the peddles and floor hump.

My question is would my car drive like a truck with this truck setup?

Whats the difference between a truck and car manual three speed?
