I'm doing a disc brake conversion on my 65 and it was going good untill I tried to transfer my drivers side steering arm. I did a search and see where the were two different size bolts used to attach them to the spendle. The kit uses the larger bolt and my car had the smaller one. Not much difference in size, can I drill the holes out or do I need to find the correct arm? The passenger side has the correct steering arm for the conversion. If a new one is needed any idea on where to find one?

Drill the hole out to fit the larger bolt.

Thanks!!

Second the last post - there is plenty of meat to drill safely. The forging is the same for both.
