i'm looking for a drive shaft for my 91 dodge d150 shortbox. i just installed a 318 with a 727 transmission. the drive shaft needs to be 48" or 4ft from weld to weld. any ideas of what dodge vehicles i could pull a driveshaft from would be appreiciated. i have the smaller universals.

 

Any decent drivetrain shop can make you one. Much safer than using another junkyard one. Not too bad of a price either, around $100 for mine if I remember correctly. They can re-use your yokes or install new ones.
Place a u-joint cap in the yokes and measure center of u-joint cap to center of u-joint cap, for the correct length measurement. The weld to weld length may be different due to different length yokes. Leave about 1 1/2" for travel at the front yoke.

 

i am planning to cut and weld my drive shaft to temperarily work and if i can find a drive shaft 48'' weld to weld i will use the same yoke. there is no place localy that do drive shafts so it will cost at least 200.
