Differential U joint

[tscott9330]

I am trying to find out if the ujoint coupler that bolts to the pinion shaft is a standard GM 10 or 12 bolt piece? I am trying to see if the u joint cap that jegs sells will fit my coupler. The Adress is http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=1153&prmenbr=361


They call them U joint Girdles and I am trying to figure out which one will work, if any. My best guess would be the first on the list, the ones for 55-82 chevys with U bolts.

Thanks,
Tom

Tom-
I know there are two different sizes; because my 4.11 s in the '66 uses a different U-joint than the 3.08s in my '69. What this demension measures, I don't know. I do not have any pinion yokes loose to measure.

???????? Sorry
