Left hand conversion kit shouldn't affect the compatibility of the trigger assembly so you should be fine with any left hand kit. But if I were to be in your position, I would just dremel a new bolt slot onto its left side and so I only need to buy the left hand bolt.
If your receiver is 2 pieces (has the tail, the part which your bolt would lock into, separated from the main body), then you would only need to change the tail, which should be cheaper than to buy a whole left handed receiver body. Novritsch has this for like $30, you might want to try your luck (because I don't know does it fit or not)
