Any leads on where to look for stock handlebars for 1979 CX500 Standard? Or knock-off bars that are a similar shape? Don't particularly like/fit buckhorns or clubmans or clipons. Any help appreciated!

Looking for handlebar clamps to replace the fuse block combo that is on the stock 80 Deluxe. Not using the stock ignition switch either .

So I stripped 2 of the 4 Allen bolts on the handlebar clamp. I'm trying to replace my bars. Does anyone know how to get these things out without ruining the thread? The bike is a 1981 CX500C.
