Wasting your time to try and make that swap... 3v and 2v don't play well together.. 2's and 4v's work.. but 3's are the odd man out...

All that being said, you might be able to get it to fit with some adapters, but actually getting it to work is a whole other story...

If you want a L motor, buy an L motor, or a 2v and make it an L motor...

My 2¢
