Default Slave cylinder problems 1989 6 speed

I have an 89 6 speed and I’m replacing the slave and master cylinder. The master cylinder went great but I have had some issues with the slave cylinder.

Above on the left is the new slave and the right one is the old one, from what I can tell the bleeder was removed on my old slave and when trying to put in the new one it hits the bleeder and doesn’t allow it to go in. And if it went in I would not be able to reach the bleeder anyways.

1.) What I’m thinking is maybe I have the wrong part?? Even tho it is the same one that was in the car previously but with no bleeder.

2.) I need to flip the slave upside down and have the brake line come in from the bottom so the bleeder can be available. But not sure if the line will reach that. So I may have to make a new one??? I have no ideas really. But something’s not right.

3.) am I able to swap the bleeder to the other spot?? That might make it viable but idk if I’m able to do that.

What I did on my 89 was to bleed the slave with it not bolted up. IIRC I started with a gravity bleed and the bleeder pointed up, this got a lot out. I also used a large block of wood while under the car and pushed the plunger numerous times with it in different orientations, I believe I also pushed it against the block to help it bleed. It has been a few years since I did mine but I was able to get it mostly bled that way, enough to function. They are not the easiest to bleed and once it was bolted back up I pushed the pedal a lot to assist bleeding. It continued to self bleed for a few weeks after and was normal again.

Get as much air out as you can before bolting it up, then use the pedal to help the last bit of air to move up.

Did you have to remove the bleeder?
Right is old slave. With bleeder removed. Bc it hits floorboard and cannot seem to fit in with it on. Did u leave it on? Does ur slabs look like this?  Thanks

No, the bleeder was only loosened to allow the air to escape. I don't remember the orientation of the bleeder after installed but it was still accessible.
