It's hard to say why it was replaced in the first place or what it's off of. It doesn't appear that this one "works" at all.
My opinion...
-Either replace the perch or the lever.
-The geometry is off and from what it sounds, you're inducing slack in the cable just to be able to reach the lever. Probably not good all around.
-Find a used perch out there. Start by IM'ing PaulPud. I bet he has one for you.
-Now I'm curious what your brake side looks like...
This is what I thought you meant before...Functionally still OK.
The brake side is stock I do believe. It looks oem anyways. Everything works perfect on that side. I will IM Paul and see if he has one. Thanks 50dro! I have plenty of time before riding season to find one. If not ill throw the old lever on! I still have it lol
