A buddy gave me the driveline from a 67 F100 for the Model A hot rod project this weekend. Bellhousing and tranny bolts right to our 302, so all well. The truck's inline 6 slung a rod, but the tranny is good and he had just replaced the clutch. However, the tranny uses a 2-piece driveshaft (no slip yoke). Any thoughts on using a 2-piece driveshaft in a hot rod project? I know rock crawlers don't like slip yoke setups, but we'll be sticking to the asphalt with this ride. We're still working on the chassis, so adding a driveshaft support shouldn't be a hassle at this stage. But are there other things to consider? Rick
Most transmissions convert back and forth from fixed to slip yoke with nothing more than a yoke change. Maybe you're doing the driveshaft yourself, but if a shop's doing it the single shaft with a new slip yoke ought to be cheaper than a dual shaft/fixed yoke setup. Besides, yokes are a wear item anyway due to seals wearing grooves. good luck
Transmission to rearend distance is short. No need for a 2 piece driveshaft. Remember the old phrase KISS.
2-piece drive shafts are usually used on vehicles with a much longer wheelbase than a Model A or T Ford. and they DO have a slip joint at the tailend of the front shaft. If there was no joint the shaft would bind up during suspension flex.
Ok Lets see here .You are gonna use a two peice driveshaft for roughly 38 inches,Spend the money and go to speedway for about 85.00
my drive shaft is 30" long..on my A build with SBC and 700r4..I wouldnt even think of trying to run two short shafts for this distance..I think your asking for trouble..more shit to go wrong.. 1 shaft, you'll be golden
What's the Speedway part? It was also suggested that I check with a local driveshaft shop about havin g a single-piece driveshaft built with the slip in the shaft, so it'll bolt up to the fixed yoke.
Let go of the fixed yoke man, it's a $30 part. Just let it go. Like it or not there's probably zero useable parts off that driveshaft for your application. Forget you own it. It's only use is to confirm the spline count & seal diameter for the transmission output. good luck
First question here ,is this a 3 or 4 speed trans? If the 4 speed totally unsuitable for rod use. Having a one piece drive shaft with the slip on the shaft is OK not any problem. Go talk to a drive-shaft shop for options.
I run one in my '34 Plymouth couple my '47 Ford truck an dmy '64 Rambler- all with The Chrysler Cast Iron Pushbutton transmissions. It's not that I have any love for them - it was just the easiest way for me to get them going. They ARE expensive to replace but if you already have the pieces parts and they're in good shape I don't see why not - use them.
