I've had to replace the drive shaft yokes on my 1973 Hawke Formula Ford. Unfortunately, I cannot find the original yokes, or similar castings, so I've had to get some weld on yokes from Hardy Spicer, and machine them to suit.
Unfortunately, these yokes are a little thinner, and the spline edges are very close to the outside of the casting. Indeed, a previous one cracked in service.
I'm thinking of just grinding out the real thin part, so to totally eliminate potential cracking. What do the experts think?
Original on right, cracked one on the left, and just machined in the middle.
