New replacement shafts will cost a easy $250.
IF you bring you shaft to a driveshaft specialist with a spare driveshaft for parts they can lengthen it to any thing you need for $50 plus $50 to balance it. IF you don't bring a spare driveshaft he can get the new parts needed for $130 plus $50 to do the work, then $50 to balance it.
At least that is the cost of my local shop.
The front would only need to be shortened, which wouldn't need a shaft for parts, and would only cost $50 for the work, and IF you want to balance it, it'd be another $50, but the front doesn't need to be balanced unless you want to drive it on the road going 50+mph with the hubs locked in. But you said you already have a front shaft that should work, so it doesn't even matter.

Just put 2 rad hose clamps on the drveshaft after redone move them till smooths out. (balance) I do this when I cut down shafts .For low speed trucks.
Do it yourself
Figure out length
cut shaft and grind welds off yoke and remove extra shaft
cut driveshaft square
fit yoke and weld in (my welder charged me $20 )
use the 2 clamp trick (bolt acrossed from one other) Or just get balanced
Take for ride and see move the clamps towards each other one way or other till drives smooth.
leave alone or have balanced .
I done this several times on my plow trucks when swaping rears ETC. Lost
