drive shaft

Is there a one piece drive shaft that will swap in place of the two piece in a 67 F-100

anyone have any experience with this?

you could look at the dentsides. it might work. i havent done much on measuring on the driveshafts. but you measure them from center of ujoint to center of ujoint. and then measure both yokes to see if they are the same length. that should give you a total to see if any fit.

isnt there a problem with puting a one piece shaft in place of a two piece?? wont the ont piece have a tendancy to "whip" or vibrate bad

they must have solved that problem with the dentsides. because all of the 2wd lwb dentsides i have seen all had a one piece. i do remembeer hearing something abotu what you are talking about though. but i dont remember what it was.

Don't know about the bumps but my 63 uni longbed, 390/C6 has a one-piece driveshaft and has been paced by a known good speedo in a new car at 120 mph with no vibration.

Yep, the 79 LWB I scrapped had a 302/C6 with one piece driveshaft... the only thing with it was the trans had a slip yoke in it instead of the yoke mounted in the trans. You can convert over to a 1 piece but you will have to convert over the trans for the slip yoke as well. This is one reason for the 2 piece driveshaft as the slip yoke is in the shaft not the trans.
Some of the newer crew cab short bed trucks (gm) switched to a 1 piece shaft to get rid of some vibration problems from the 2 piece they had before.

Anyway, Hope that make sense...

Yup, that all helps

It's a 302 with a C-4 so I'm gonna scrounge the boneyards and make something work

Forgot to mention the uni has a car-type slip yoke trans.

Only the lightest duty Ford long bed trucks got oe piece shafts, all the heavier ones got a two piece shaft. Do a search, we discussed this subject a while back and a lot of facts were posted. Hawkrod

I can't remember the cut off point but most driveline shops recommend not going over a certain lenght for a 1 piece. I'd be a little skeptic myself, but you're not me.

Give it a shot!

When I swapped out my 302/FMX combo for a 302/C6. The truck had a 2 pice with a slip yoke on it and the truck the C6 came out of was a 2 pice slip yoke also. So istead of messing around and wasteing another $111.01

I just borrowed the one pice out of my brothers 84 or 86 F150 and it fits like a glove. The olny thing is the front of the driveshaft rubs the carrier berring mount. So if you go one pice I would suggest cutting that out,but make shure the one pice fits first

.

Also I got a question why did some trucks use the blot on style yokes and cars don't?
