Ford 8.8 - Mustang yoke?

I just ordered a driveshaft spacer for a Ford (mustang) 8.8. It turns out, the pinion yoke/bolt pattern is smaller?

I am currently running the spicer adapter that I purchased from MORE.

Does anybody know which size u-joint this Mustang yoke uses? I was wondering if it's 1310?

mustangs and rangers used 1310 joints. when i put the 8.8 in my mj i used a flange adapter from a ranger. this means no adapter joint like most guys run.

I snagged one from a mid 90s Grand Marquis. Same thing, bolts to the pinion of the 8.8 and accepts a 1310 joint.

Same thing happened to me! Well, one of my friends gave me a driveshaft from his 90 Mustang. It has 1310 joints, but it doesn't fit the pinion flange either! I was all excited when he gave it to me, and I called the stealership so I could give you guys the part number and everything, then I realized it doesn't fit! I am a little bummed to say the least. Also, some of the Mustangs use a 1330 joint, so watch out for that. That is the same size as the Explorers.
