Default 1980 differential question ( experts please )

Hi guys... I know 1980 auto used the 1330 U jonts ,, 1981 4 speed manual and all of 1982 used 1350 U joints meaning they had the heavier yokes , stub axles and dive shafts yoke ends.

My rear was upgraded by last owner , all 1980 to 1982 use 3 inch drive shafts which I have .. SO HOW can i tell if I have the auto 1330 u joint set up or the HD 1350 u joint set up ? ? ?

Thank you in advanced

Screws on U-joint caps on 1330s are 1/4", 1350s are 5/16".
