OK, I’ve done parts for 30+ years, but this one is pissing me off. Long squirrel (literal) story short, I have lost a single U Joint cap strap that attaches the drive coupling to the output pinion yoke on the transmission.
The joints are Cleveland R55 series(inside lock), which are obsolete, but have plenty of alternate numbers. They are typically used in a 1350 driveline application. The key fact is that the caps are 1.188”. Chasing this back thru a Spicer number(5-1205x) gives a cap number of 3-70-28x. Not even close. The arch is too tall and the hole C/L to C/L is too narrow. Standard 1350 setups are outside clamp locking, not “C” clip with the narrow strap. The straps I've chased so far for a 1350 yoke attach centerline with the bearing cap. As you can see in picture 5 below, the stock yokes over shoot the centerline.
That got me to thinking the output yoke was actually based on the 7260 Dodge driveline. But those caps only measure 1.078”. And since they are all “C” clip they don’t provide a strap number. Of course, unlike most every other part, there is no casting or stamped number.
The strap I need is:
1.875” hole center to center
.375 from flat surface to highest inside arch point
.562 strap width
