Finishing up a big block Chevy build in an 86 Olds 442. Need a drive shaft for a short tail shaft turbo 400 to a Grand National 8.5 rear end. It's a street car. Anyone have any ideas outside of having a custom shaft built?

Determine the length of shaft you need universal center to universal center with your yokes and put a call out. New shafts aren't that much and you can always have yours cut. I believe the 400 is aprox 3/4 inch longer than that your original trans so yours should be close.
I had my driveshaft cut and balanced, after that was done when I found out it would have only cost me another $80 to have a new shaft I could have kicked myself...
Ebay "nascar drive shaft"
Bunch of old race shops dump 3.5" 1350 U joint shafts for cheap. I got the one for my 2+2 for under $100 shipped. I did put new U joints and a slip yoke in since they come T400 output and I had a t56, but its a good option if you get lucky and they have the right length.

Got mine from Southwest Speed. They ship same day as they have all lengths in stock. I'm also running a TH400 & GN 8.5. These are all 1310 u-joints but they do carry a conversion joint for the rear and these include a new slip yoke.
