1970 u-joints

I am looking to replace both of the universal joints on the two drive shafts n my 1970 cj5 v6 t86a, Dana 18 (single stick and parking brake ) with a Dana 27. Front. And Dana 44 two piece rear. I have searched and read a lot on this site
but still unsure of what sizes of universal joints to. Use. Can anyone point me n the right direction?

 

I can't remember what part numbers but I went into my local napa and had them find the ujoints for me

Or just order from walcks or kaiser willys no need for part number

1310 is what I remember but my napa store didn't know what I was talking about

If you do a search it should come up with part numbers.

 

I have been using the search. Function. On this site with little to no luck, local parts stores are saying its the equivalent of a precision 365 on all four, which from what I've read and seen cannot be true since both front u joints are smaller. Anyone?

 

The rears would be: Spicer 5-153X
The smaller V6 fronts are: Spicer 5-248X.

 

thank you jpflat2a
found them all instock at a small parts store 45mins away
