I have a set of NOS 14mm ball joints that will not fit the 01/70 restoration due to the 11mm taper receivers on the lower control arm steering knuckles. What do I do? 1) have the OE steering knuckles tapered to accept the 14mm ball joints and pretend it never happened 2) purchase 14mm steering knuckles (are there noticeable differences?) and pretend it never happened 3) find NOS ball joints with an 11mm taper 4) buy AC DELCO 11mm taper ball joints (are there noticeable differences in appearance) originality is of most importance, but if the 11mm taper is a safety issue (as it seems, due to the change in size), I would like to know what the best solution is as far as a resto goes. my spidey sense tells me that any NOS 11mm taper ball joint I come across is going to be rusty, sloppy, or not worth the cost.
