Can anyone tell me what u joint I need for my 1949 ford shoebox? I have the original driveshaft and i installed a Maverick rear end. Thanks for any info
You need to measure the yoke on the Maverick rear end. Typically that would be a ****er 1310, but you need to check. That would have 1-1/16" caps, with a cap width of 3.219" (sometimes listed as 3.22"). Ford sometimes swapped parts, so it is not a guarantee that we can guess. The original u-joint would have been a NEAPCO 1-2134, or equivalent. Specs are here: https://www.dennysdriveshaft.com/p9...sal_joint_2crl__2r_fits_1949_1959_ford_a.html The bearing caps on those are 1". You need a u-joint that agrees with the driveshaft, and the new yoke. This joint may not exist.
If the diff yoke does take a ****er 1310 u-joint (but as gimpy said you have to check), the drive shaft having 1 inch bearing caps, the u-joint you would need is a Precision, or Moog number 505. I used this same u-joint when putting a Mustang yoke on the front of my '50s drive shaft to mate it to a toploader trans.
Fifteen minutes of poking around in Rock Auto, Napa and O'Reillys 49 Ford listings for U joints says you are going to have to pack the driveshaft and your measurements for the Maverick rear end to the local parts house you go to. Fords drive nuts on things like this because there too many freaking either ors or iffs to deal with. Even and maybe especially on the Maverick rear end you have to take accurate measurements or something for show and tell even if it is a playdough impression because guessing doesn't work.
I believe what you want is this..... Amazon.com: Speedway Motors 1310-to-S44 Series Conversion U-Joint, Compatible with Chevy-to-Ford Adapter U-Joint, Grooved Endcaps for Inside Clips, All Clips are Included : Automotive You'll have to check dimensions, but this should be right. Ignore the Ford-to-Chevy business, the 1310 was used across multiple car lines including Fords after 1956. Your 8" rear will use a 1310. Now whether your driveshaft length will be right is another question....

The drive shaft has what is also called a “mechanics” u joint. This photo shows the one you need to combo.
The catalog is an endless sea of good information. I printed a few pages I needed a couple of times to take to a parts store.
