Building a 1950 GMC 100 short bed. Using a 248 inline from my donor truck, stock bellhousing with a T5 from an S10 (picking up the tranny from the bone yard tomorrow)and a mid 60's truck 12-bolt dif. I was wondering if there is a drive shaft out there from another model car/truck that would drop right into place, or does everyone have a longer shaft modified to fit their rigs? Alex
