the car is a 74 went from power to manual.I went ahead and took the coupler off,and it is definately smaller.Can I just have the machine shop drill it out,and weld the adapter to the coupler?
It's what I would end up doing, however I'm not sure if you have another option. Firstly if your cars a 74....Did you "order" this adapter by year, if theres such a differance in the shaft size? Perhaps you can exchange it for the correct dia. If exchanging is not an option I believe you can redrill and weld. Just ensure you don't weld too far up the coupling shaft because you don't what the column's sliding blocks to bottom out inside the coupling when you put it together. So I take it your new adapter fits onto the steering box shaft end..that it's OK? If so, maybe now if you don't want to weld you require a different coupler that matches your adapter.. :scratch: or if it's not one thing, it's another. been there! :angry4:
