Driveline ???
I HAVE A 1969 F-250 CAMPER SPECIAL WITH A 360 V8.
IT HAS A C6 TRANS THAT CURRENTLY IS SHOT. I FOUND ANOTHER C6 TRANS OUT OF A 1971 T-BIRD WITH A 429 IN IT AND IS IN GOOD SHAPE THE ONLY PROBLEM IS WHERE THE DRIVE LINE HOOKS ON TO THE TRANS. MY CURRENT TRANS HAS A 4 BOLT FLANGE ON THE END OF THE TRANS OUTPUT SHAFT THAT THE DRIVE LINE HOOKS TOO. THE ONE I AM LOOKING AT BUYING HAS A SLIP YOKE WHERE THE DRIVE LINE ACTUALLY SLIDES INTO THE TRANS ON SOME SPLINES. MY QUESTION COULD I GET THE TRANSMISSION AND JUST PUT A DIFFERENT DRIVE LINE IN TO MATCH UP WITH THE TRANS OR DO I HAVE TO LOOK FOR A TRANS WITH THE SAME 4 BOLT FITTING? IF I WAS ABLE TO JUST GET A DIFFERENT DRIVE LINE WOULD THIS LIMIT THE AMOUNT I COULD HAUL OR PULL IN THE TRUCK OR NOT?
THANKS FOR ANY RESPONCE

You would be surprised how cheap it is to have a custom drive shaft made by a local drive line specialist. I had all new heavy duty shafts made for my truck. The shafts were made of large diameter tube fitted with heavy duty yokes and splines all balanced and painted. Much beefier than stock.
The rear shaft setup ran about $115 and the short center shaft was about $85. You should be able to get out for well under $125 for everything.
It's up to you to make sure the length is right. It would be best if you can supply the mating spline to the replacement tranny if it's not too worn. Make sure that if you bottom out the rear suspension that you don't bottom out the yoke. You may have to do some geometry calculations.
I hope this helps.

jskier, putting a used tranny in your truck and having to spend money to make mod. don't make much smarts. My suggestion is either rebuild the tranny yourself or send it out. You would be really pissed if after 3 months the new install died on you.
If done correctly a new rebuild should last for years.
good luck

I'm not sure if you were considering an engine and tranny swap or just the tranny. If it's just the tranny, hold the phone because the C6 on the 429 will not bolt to the 360.

I have to agree with Stockman in that it takes an FE trans to mount up to an FE motor. Beyond that if you take the slip yoke from the trans you're going to use and get a U-joint that matches both the yoke and the driveshaft you're going to use, then you're in there. What I wound up with is 2 slip joints. One at the trans and one on the driveshaft.
