I have been told a conversion from an early bay steering box to a late bay one is possible. I have been offered one of each from different people, for the same price. I have to decide which one to go for. I'm not sure how to put it all in sentence form, and structure it enough so people can understand - so i'll just list all the factors. 1. First things first, I need to make sure the conversion is possible and easy enough (no mechanics will want any part of it). 2. I'm not sure on the safety/reliability/legality of the conversion. 3. Both would be purchased unseen (not that I even know what to look for). 4. Late bay steering boxes can be rebuilt, early ones cannot. Please help me pick which would be the smarter option!
