Hi Mike.
If it's easier to get to on yours can you measure count the following?
Steering rack pinion teeth and diameter. Mine has 17 teeth and about 15-16mm in diameter.
Steering UJ number of teeth and diameters. Mine has, as far as I could tell around 19. But other half made it around 28. But was very worn both ends. 28 makes more sense as follows.
Count column teeth and diameter. Mine has 29 teeth and around 15-16mm. Pictures...
Flat section as well.
I'm looking at getting the correct UJ made for both rack and column. So if yours is the same as mine, I can get another ordered. If it's possible.
