tim, I did the same swap with a 4spd. and had to shorten the shaft 1''. I'm not sure about and auto trans, but I don't see why you couldn't use your shaft for what you want to do. glen

This is not the same setup as you have, but I went from a ('73) C-4 with a 6-3/4" to an '88 TC T-5 with a 8" and I did not need to change the shaft.  IF your C-3 is similar in length to the T-5 then it seems that it should work.

Thank you all for the help. Hoping all will work well. No drive shaft shops close and funds are in short demand. Merry Christmas to all.

Jack car up UNDER REAR AXLE TUBES with driveshaft installed. Make sure it can't roll on you. Mark or measure where installed driveshaft stub goes in trans right at the seal. Then pull back of driveshaft loose from rear end and then take shaft and slide it further in (too far) in back of trans till it hits softly and measure again and determine the difference in the two numbers. You need one inch firm to allow for in/out as the suspension works in normal use and that also guarantees the stub is in far enough. If less than one inch and you hit a really big bump or pothole, stub will go in far enough to knock out the stub end plug and kiss all your ATX fluid goodbye, you find out when trans locks up from no fluid in it.
