Fitz's post reminds me; I didn't answer your question - I agree about Spicer - also their site has lots of manuals and tech info about their products.

Probably you would have to remove all three U-joints and measure them before you will really be certain exactly what sizes to order. On mine they were all the same - 1310 Spicers

Spicer has a Youtube video that shows the grease flowing through the zerk and joint - that video helped me to decide which type (greasable vs non) to buy.

On the Spicers I bought from that hot rod place in Nevada the crosses were made in China (not a problem - hey China was doing cast iron when we westerners were still swinging from the trees over in Europe)

And all the other parts of the Spicer U-Joints are USA made
