Pretty much finished up on the rust repair, just need to clean and paint it with some Por-15. I used some fiberglass filler called Long N' Strong on the smaller rust holes, highly recommend it. Just spread it over and sand it down.
On another note I found out I have to take my cases out again. I didn't grease the input/coupler when I put together my duals which can cause fretting. Shouldn't be too bad though, don't have to tear them down just pull them apart. Hoping to get everything done tomorrow.
