If tank turrets are more common I might use those more but not too many on the map,would a leopard 1a3 class as an old tank I can make into a tank turret bunker?

Just take whatever old tanks you have lying around, dig a large hole, put your tank at the bottom and pour concrete over the hull!
You can pretty much put any tank (or other AFV) you want, even modern stuff even though it doesn't make sense stores-wise.

"And most bunkers now would be shelter or machine gun positions" So there should be more of them then any other bunker on my field.

You can consider your defensive line as normal troops heavily fortified. Therefore you can keep the same proportion of armor, infantry, artillery, air defense etc. (in fortified equivalent or fortification troops) as when buying for a regular defense. Replace one infantry squad/platoon with one LMG nest/ earthen bunker, infantry support with MG nests or ATGM positions, tanks with cannon bunkers...
You're free to customize, but IMO this could be a working basis for a balanced defence. Just food for thought.

If I put infantry inside a shelter bunker will the computer unload them?

Not sure at all.
Try giving the infantry formation a reaction turn, they may move more easily.
