Brazing aluminum zinc die casting ?

[TxCajun]

The shift lever holes on the "Shift Lever Housing" for my 1966 manual shift column are worn out oblong and cracked, so the shift lever roll pin which should be pressed in is just a wobbly fit.

Can these holes be repaired with aluminum brazing rod and then re-drilled? It appears that the commonly available rods have a melting point of about 720 to 750 degrees, but I have no idea at what temperature the die cast would melt or distort.

I also found ads for a brazing rod product called Muggyweld that has a melting point around 350 degrees, but the cheapest "kit" of rods and flux is around $50.

I was also considering a JB Weld repair of this area, but it seems that there would be a lot of stress at this pivot point. The JB Weld claims a strength of about 4,000 psi whereas the aluminum brazing rod is closer to 20,000 psi.

I haven't had any luck finding a replacement "Shift Lever Housing" locally or online.
