Brother LS-1520 sewing machine.Bottom bobbin thread gets caught and has 3 threads coming up! Driver is pitted?

I have been looking for replacement parts without any luck. I know the driver is pitted from a bent needle that wasn't my fault. The clear disc that sits under the top thread spool was not completely glued onto the machine when it was new. The thread got caught between that clear disc and the top of the machine and bent the needle, causing it to hit the shuttle hook and pit the driver, before finally breaking into 3-4 pieces and hitting me in the face. I was unhurt, amazingly, and thankfully. I was new to a sewing machine at that time, but I've gotten over my fears and sew regularly. This LS-1520 is my back-up machine. It doesn't help to have a back-up that doesn't work. I can wind bobbins on it.

The problem is that THREE threads come out of the bobbin area. The excess loop of thread, created by the two extra threads) catches the fabric and causes it to quit moving. I get a huge ball of thread on the back of the fabric and a hole in the fabric. I have to cut the thread and fabric out of the feed dogs. It gets bad really fast.

I have been told my shuttle race is scratched. I think the problem lies between the pitted driver and maybe it is out of time due to needle hitting the shuttle hook when it was bent.

I have done many searches on the interent to find a part/parts for this machine and on eBay with no luck. I am in a very rural area with no repair technicians that I'm aware of. I think it would be wise to fix the machine myself or just buy a new low-cost one.

Where can I get a driver? It's the little black curved piece that doesn't come out of the shuttle race when you take out the bobbin, hook, and shuttle.
How can I time my sewing machine?
