55.2-59 Best Driveshaft to cut down for LS swap and C4 Vette Rear

[daveshilling]

Gang, it's driveshaft time.... and I would love to re-use an old one and just have it cut down. Better for the planet, and better for the wallet.

I'm going from a 4L60e to a Corvette Spicer 1310 rear. 2.5" diameter preferred for clearance... If 3" is the only option, I may need to trim a crossmember but I can manage that if I must.

I need to get something longer than say 54" to have it cut down by a local shop. Has anyone found a good match in a used driveshaft for an application like this?

The driveline also said to avoid swaged (tapered) if possible...or to make sure its so long that I can cut that off, but trucks with super long driveshafts are usually 4" or more.
