A little time on Google shows the 1141 (12v) will cross with the 1129 and the 89 (12v) will cross with the 81. You'll need to bend the bracket just about half way between the sockets. Aim the bend toward the back of the housing. It may take a time or two to get the right bend since too little won't allow the bulb to clear the lens and too much will make the bulbs interfere with each other. It's not that hard if I can do it.
