Re: 5.3 to th400
Ok...now I get what has you stuck....
I have to assume you are using a hand drill and burs or a drill bit itself to elongate the holes....slow work at best... Do you have access to a drill press? Last time I did one of these I predrilled where the center of the new hole would need to be located with a small drill bit then gradually opened up the hole until break thru was achieved, than used a dremel bit and grinding stone to finish it off....took maybe half an hour per hole.... If you dont have a drill press, a machine shop would be your best bet.... Good luck...
