I know this has been discussed before but I can't find it. Here goes, 1960 elcamino 348 t-10 4 spd. I spotted slow drip on out put shaft. It doesn't look right, yoke is only in 1 1/4 past seal maybe 1 3/4 on the splines. measured front shaft out side of u-joints 25 1/2 inches total length. Is that where you measure. Center carrier bolt holes lined up so back section must be right. Motor/tranny bolted in stock mounts.
