Well today didn't go as I had hoped transmission is in the same point as it was earlier. I got the case put together but when the tail shaft was installed the gears wouldn't turn. I'm assuming that I didn't have the #4 gear indexed correctly. I took it all apart and put it together without reverse stuff and it worked good. Luckily I have a spare set of gaskets i will attempt again either tomorrow or wednesday.

Well I need more advice this time. I got everything put together and everything turns as it should and everything feels good.
The 1-2 shift is rather hard is this common for a new slider and new keys? I can get it into gear but have to nudge it with a screw driver. Also the input shaft has a little play in and out is this common or is the front bearing not fully seated on there?

Dont worry if it feels stiff.
The input shaft should have no play in it. The front bearing rides tightly in the case. The bearing retainer holds it there. The input shaft nut holds the shaft tightly to the bearing. Did you fully tighten the nut? It generally requires a special wrench. Or is the nut on backwards, I've seen people do that before.

I tried to tighten the nut as far as I could but I am unable to maybe I will have to get one of those special wrenches. Right now with the input shaft pulled full forward there is a gap between the case and the snap ring of about 1/8" I tried to get the bearing to go on farther but I'm having difficulty. If I laid it face down in the old case with the bearing resting on the face can I use a dead blow and hit the tail shaft to get the bearing to seat fully?

Dont hit anything with a hammer.
The front bearing slides in with the groove toward the front. The big C clip keeps it from going too far in the case. You put the input shaft/gear from the inside of the case. The nut goes on with the rounded portion forward. The rear of the nut has 2 flat spots to put the special wrench on. When you tighten it, it will fully seat the input shaft/gear against the bearing. Note, you may or may not have a slinger between the gear and beaing (inside the case).
Now you put the 4 bolt bearing retainer on the front of the case. The cutout for oil drainback should line up with the hole below the input shaft. Once that is tightened, there should be no play on the input shaft.
