Glad you joined us here! If you can post your questions separately on the Bally Reel Machines and Classifieds topic, you will get your answers. We have a pretty knowledgable group of members here for EMs.
I don't know what it cost to turn the hopper shelf, but can't you buy a replacement pretty cheap? And just change the shelf and coin knife?
On the glass you need, if you have pics, that would help enormously. EM glass is a bear to find, well, I guess I should say it's a bear to find the RIGHT one!
For the topper, check my website. I have a few on there, but again, finding the right one can be challenging!
I think the hopper not resetting issue has been discussed on here previously. Try searching "hopper reset", "winner paid light", and "winner paid on".
