Been there, done that. My problem came from extreame wheel hop
at a SOLO II race. Even dented the rear shocks when the rear end wound
up. Weld on Traction Bars solved that problem. I was able to "press"
the u-joint/caps out. Used socket slightly larger ID than the cap
to support one side of the yoke. Supported the drive shaft with
something ( don't remember from 1974). Used a steel rod slightly smaller than
the cap on the other side. Used a 3 pound hammer to "press" the cap
out the far side. Flipped the yoke ofer and did the same to the other cap.
This sheared off a thin "new moon" shaped piece of metal from both sides
of the yoke. The new U-Joint went in OK. Now, after 5 or 6 sets of
U-Joints over the years, I find that one hole in the yoke is just
slightly oversized and the cap in that hole can rotate. Like a fool,
I sold my spare good drive shaft to another Tiger owner a couple of years
ago. Should have kept it. My 351C puts a bit more pressure on the
drive shaft than a 260 or 289, but it still works. My problem at the moment
is not the drive shaft, but the worn out rear end. I have about 45 degrees
of backlash on the 300,000 + mile, 2.88 rear end. Working on a replacement
at the moment. This will also cause me to change the driveshaft to a bigger
one in any case.
