drive shaft questions and cost $$$$

[tommie]

tring to get closer to getting my truck back on the road.

i have a 70 swb 1/2 ton, i put a 350 and a 700r4 trans in, with the engine in the stock small block location,on small block stands, i org had a 3 sp standard, and a straight 6, one piece driveshaft.

what can i do about the driveshaft?

what does it cost to get one made?

or should i just try and find one from a junk yard the right length from another car?

what driveshaft yokes are the same as what i need for the 700r4?

just tring to get a guess on costs...

thanks
